Exactly. Why does it have to be one or the other. I like to get as much knowledge as I can from as many sources as possible. By the way, is this app available for Android, or just iPhones?

Every little bit helps
Just remember fellas, nobody knows everything, not even (ahem) me, so any help you can get playing banks certainly wont hurt you. Try the calculator and see if it helps.

The Bank Shot Calculator doesn't take questions and give answers in the scenes you're thinking about. It does however account for it all. You tell the calculator what you want to do to the shot and it calculates the point on the rail you need to hit. But Yes, It knows how much english will transfer from cue ball to object ball and what effect that will have on the rebound angle then makes the adjustment to the target line. It also knows how far the cue ball and object ball travel before any English will transfer (ball skid) based on the shot speed you select. If you’re trying to put in english that won’t have time to transfer because you select a shot speed that is too great for the distance between the balls the calculator cancels the english out of the rebound angle and adjust the aim point. You key in what you want to do and the calculator makes adjustments for those variables. Visit the website. The FAQ page discusses what I call jacked up center ball. Then we have some shots that demonstrate for you to practice.
Thanks for the questions and good luck.
Thanks Freddy. This means a lot. Honored to meet you last week. I liked watching you move on the action table. Cheers!!
Impossible. Want to know why? Because every set of balls will not have the same condition. Some will be cleaner than others, some will be god awful dirty. Also the cloth plays a huge part in banking too. Sure your calculator might useful for someone just learning to bank, but for people looking to control the cue ball after the bank, your app is worthless. Sorry.
If having a calculator to check your math is critical then you're in trouble because it isn't legal during play.
That said, I can see a couple of ways it might be a useful training aid and it's only $5. You can spend 6 times that on a piece of chalk.
Plus I note Clyde has been running ads on pool streams and that's cool.

Let me just suggest that all things are (relative). The cue ball will transfer 25% of the English you put on it to the object ball. In show room conditions like the Derby and other tournaments and in most pool halls I’ve been in I’ll get two diamonds deflection with one tip English of center at the equator. That same shot into an object ball returns ½ diamond deflection. If therefore I find a table that nets me 3 diamonds with the cue ball I would expect that same stroke to net .75 diamonds of deflection on the object ball and therefore would adjust accordingly. You are correct in your assessment of changing conditions and equipment and I accknowledge this on my website www.bankshotcalculator.com, but the physics don’t lie.
Many thanks for the dialogue and good banking. Keep Hiting-em-Hard,
Cheers,
That's quite the assumption there.
Changing conditions means any system you use is only as accurate as your understanding of the conditions on a particular day. That's an argument against systems in general, not any one tool.
I'm in the "spend the $5" camp.

I did not get the count but how many players were at the Derby? I'm thinking just over 400. Market research statistics suggested over 44M people play pool. I'm guessing most are in trouble as you suggest. I just want to help get them to a level they feel like competing with all you guys on this forum. If I can do that for 5 bucks I'm putting more revenue into the sport for everyone else. I appreciate you recognizing that with my ad monies. Man, the ad monies, they do ad up. On that note I came here for help. It stands to reason I would have to defend my position. I expected that. That's you guys keeping the riffraff out and I applaud you all for it. But this app is the real deal. Out of respect for their profession I will not mention names but it was warmly received by some of the players at the Derby. If you know any personally please ask them if they saw it. I’m confident they’ll speak well of it.
Cheers Dog, and Thanks,
Buy the calculator it can show u thing or two but as has been said it isonly a practice tool. Also the same is true for the dvd or books these are for training and building your knowledge
Best investment u can make is time on the table. Hit alot of balls match up play on different equipment
People trying to do something for pool whether a dvd or an ipod app are trying to help but only u can make it your own
Good luck banking

all tables play different some play short some long the calulator might help but it won't tell you if the table is wet or dry think freddy had a story in his book about a bank eddie taylor done on a wet table

Disclaimer: The physics of pool and billiards dictate that every player, table, room, felt, cue stick and numerous other factors cause different reactions when striking balls and rails on a pool or billiard table. The Bank Shot Calculator simply calculates the point on the rail, taken from where the balls are plotted on the screen, which creates equal approach and rebound angles at the rail. The end user must determine the correct speed on a given table using desired amounts of spin on single and multi-rail shots. I will attempt to give some guidance on these shots on this web sight.
I'm with you Willie, could not agree more. But, are you talking about the rule, or the exception?

Isn't this the whole selling point of your calculator? Making it so people can more easily understand how to make a bank, but you just said that one must use judgement to determine how hard and what english to use. Counterproductive to your selling points.
Just hit-em-hard dude.
I think there is a bridge that is unguarded somewhere.... get back to work.
There are tons of kick and bank shot aiming systems out there, and there are many excellent books and DVDs that can help you learn the basics. However, if you don't develop a feel for how to make adjustments for the various bank and kick effects, the "systems" will sometimes disappoint you.
Good luck,
Dave
You're description doesn't agree with the physics. Spin transfer between balls happens immediately at the moment of contact just like throw (they're two aspects of the same frictional effect). There's no special distance the balls have to travel before the transfer completes, as you suggest.
Shot speed does reduce throw - and therefore spin transfer - in some cases, but all the magic happens at the moment of contact between the balls. If anything, shooting harder is necessary sometimes to keep transferred sidespin on the OB when it's far from a rail (length of the table straight-backs, for example).
In other words, there's a tradeoff between spin and speed related to distance of the OB from the rail. Shooting slower results in more spin transfer, but the OB loses it over a shorter distance. Shooting harder transfers less spin, but it stays on the OB for a longer distance. So some shots result in more OB sidespin at the cushion when shot softly, and others when shot faster. Additional complications to the art of banking involve the fact that stun transfers more spin than roll, too much CB english actually transfers less spin to the OB, etc., but that's a whole other discussion.
Anyway, the OB does take longer to develop forward roll when it's struck harder, which may be what you're thinking of when you mentioned "ball skid". However, that's not the result of spin transfer between balls, it's the result of friction between the ball and the cloth.
It's also possible you're trying to describe how the OB's spin/speed ratio is increased slightly at the cushion by the OB slowing down to achieve that forward roll. Still, the absolute amount of transferred spin happens at contact, so "english that won't have time to transfer" still doesn't make sense.
I think you are trying to address some practical effects in your software that you've noticed at the table, but your physics explanations could use some work. I recommend checking out relevant articles by Bob Jewett or Dr. Dave to explore the details more. Good luck with your app.

Versus? Isn't the bank shot calculator $5? I'd say get both.
I just got the Brumback DVD and it just upped my banking knowledge by a lot. But, IMO, it's not for beginners. You already have to be able to play and read in between the lines.
Big thumbs up for JBKY!!!!
