When I was playing 3C 4 or 5 times a week for 3 hrs. per day a cube of chalk (I carried and used my own) would last well over a year. But although I chalked before every shot, I am a very light stroker, practically caresser, of chalk, not a grinder, so I doubt I am using too much.
I never watched much 3C. The few times I did they would play for hours and never make a ball. Hell of a safety game both players had! As a side note, Efren pursued 3C and other carom games for awhile when other action got very hard to find. People have noticed him really shooting 3C on a pool table with pool balls warming up for big pool matches!
I didn't say all players chalking every shot use too much chalk as I am sure some chalk as you do. Seems like many snooker players chalk like that too. A cube of chalk would last them a full event and still be almost like new. Most "chalk as part of their preshot routine" players at the local hall seem to be high C, B, players and above. Some pick their tip with a tool that drives needles deep into it every session and make chalk fly every time they chalk. They are great for a cue mechanic's business.
I wipe my tip clean on a napkin or paper towel, preferably slightly damp, before putting it in my case. Then before every session and maybe once or twice during a long session I roll dents into my tip with a lot of pressure using a BRAD tool and not letting it slip. My single layer tips, Elkmasters, last for years.
The tip tools that cut a tip to a perfect nickel or dime shape with the cutout on the side to check tip profiles are great for mechanics, an ardent admirer of those can go through a high dollar tip every month or two! At one time I thought about giving one free with every high dollar tip install! I did carry one in nickel and dime to show customers what radius they really had on their old tip before changing it out and checking what radius they wanted on their new one. \\
My tips naturally shape to a little flatter than a nickel. When I stubbornly try to force them to maintain a dime shape I go through a lot of tips too! When I taught customers to roll dents instead of a bunch of other tip manicuring it cut my tip business about 75%! Another business killer, quarter radius or flatter on a break cue. A surprising number of people cut break tips to a dime shape to match their shooting cue. Why? Better break force transfer with the broader area and few use a lot of spin breaking balls. I did for years but that was before break cues were common.
As an old player and mechanic I almost never wear out a tip. I get curious about a new fad tip sometimes or want knowledge to give feedback to customers that ask or I would get two years or more out of a tip even playing heavily.
Watch how Ronnie O'Sullivan does it.
The torpedo tip was shown to me a long time ago and I can't deny the logic. Center tip doesn't need grip. Impact should be dead center ball. When striking off center it's not the center tip striking the ball. Perimeter chalking is where my attention goes
Perimeter chalking is exactly what I do too. I have never miscued hitting center ball. A very light chalking across the center once a game is really more than I need to do, then I focus on the perimeter if I have to use extreme spin. Most eight, nine, and ten ball games chalking once before starting a game using Master chalk is plenty. One pocket, depends on how the game plays out. I am pretty extravagant with my sixteen cent chalk and may chalk several times during a game for no particularly good reason!
