tip to CB contact lasts 1/1000th of a second...any deceleration of the cue stick in that tiny of a time frame is virtually non existent...
Tip contact last appx 1/1000ths of a second assuming you are using a medium tip, but is appx 2/1000ths sec with a soft tip and 5/10000(ten thousandths) of a second with a very hard tip like phenolic. Contact time decreases slightly for faster speeds. With a slow shot speed(appx 3mph) using a medium hardness tip the cue ball will travel appx 53/1000ths of an inch during tip contact and at medium speed(appx 7mph) it will travel slightly over 110/1000ths of an inch in the same time frame. As you can easily see 53/1000ths of an inch although a very small distance makes a noticeable difference in shot speed.
The speed the cue ball obtains from contact of the cue tip is not determined strictly by how fast the cue is moving but rather how far the cue ball is moved during the time frame of the contact period. Deceleration of the cue during tip contact occurs at two places...the tip as it compresses and at the grip where the cue shoves back against the hand. If the distance the tip compresses and the distance the cue pushes back against the grip adds up to at least 18 thousandths the cue will effectively slow down by 1mph which certainly could have a noticeable affect on the outcome of a shot. As you can see from the attached pic the tip alone can compress more than 18 thousandths. If a loose grip gives as much or more curing contact as the tip does it has the potential to effectively slow down the cue more than 1mph. IMO if the grip is held loose it will give quite a bit more(3 to 5 mph) than what the tip will compress using a medium plus to fast stroke. While tightening the grip cannot keep the tip from compressing it can prevent the cue from sliding back against the grip thus retaining more of the cue speed throughout the contact period.
you have a collision at a given speed. that is instantaneous...anything you do with a cue stick that takes effect after that collision is irrelevant..
The problem is that the collision in not instantaneous and varies anywhere from 5 tenthousandths to 2 thousandths of a sec depending on the hardness of the tip. The effective speed range for a medium hardness tip is from 0 to 25+ mph for that brief 1/1000th of a second contact. If 1/1000th of a second is so insignificant how can anyone possibly manage to control such a widespread speed range of cue ball speed simply by shooting softer or harder. After the contact has ended I agree with you.
the shooter has no control over anything except where on the CB and how fast the stick is moving when that instantaneous collision takes place..
If that was the complete truth it wouldn't matter what angle the cue tip strikes the cue ball as long as it hits the correct spot on the cue ball. Directional control of the cue is also an important factor.
a super soft tip compared with a very hard tip might have a minor effect.. adding in the neighborhood of a ten thousandth of a second to that contact..
Sorry but a soft tip can double the contact time from .001 to .002 of a sec http://billiards.colostate.edu/threads/cue_tip.html .
but adjusting grip or stroke to adapt to those tiny factions of a second isn't going to get you very far...especially once you add in the effects of chalk,,, how clean or dirty the cloth and balls are... the heat and humidity in the room ...
According to your definition above there is really no such thing as stroke..."the shooter has no control over anything except where on the CB and how fast the stick is moving when that instantaneous collision takes place.."
adapting to conditions is hard enough without trying to adapt your stroke and grip to any given shot... you'll end up chasing your tail.. and never get anywhere...
I don't believe I advocated what you are implying. I simply offered a solution to help correct the problem the OP was having with the draw shot. The OP has to adapt in some fashion or he will lose his draw shot. You should not close your mind to new techniques that could advance your game without even giving them a try.
a better method is to have a proven stroke and grip that you can employ over a range of speeds and adapt that way..
There are a lot of different methods that work well in the game of pool. If your method works well for you then you certainly should stick with it.
less variables equals less things to go wrong...
Absolutely have to agree with this one but on the other hand a closed mind results in a dead end.
