@iacas will be happy as this is mostly LSW stuff . I tried to add a few new ones in.
"Keep your head still" - continually hear this on the range and hate it every time.
Lay up to a comfortable distance rather than reducing distance as much as you can safely
'If only all my other swings were like that swing' from a 28 capper. They are, you just got lucky with that one...
Over 50% of your shots are from 100 yards and in, therefore practise more putting and short game. It's mainly the putting idea that gets me, but that stat is horribly misinterpreted by so many.

I gotcha. Well, the scenario you mentioned where a player starts with 30 balls and whittles them down until there is one left would be what I consider a good method (realistically you could probably start with less, but I get your point) and some players may be able to successfully do it this way, but I'll bet 80-90% of the time the ball that is chosen isn't the ball that fits them the best out of those 30.
Regarding Bridgestone's method, I just explained in detail that the fitting doesn't stop with the driver, the other shots/clubs are not disregarded and it's more shots than fittings with other companies. When robotic testing is done, everything is highly controlled and set up exactly the same for each shot of a test, but player testing will always have slight differences which will happen just like when playing. How would things like tee height and ball position be kept consistent in the method you outlined?
2/26: Worked on clubface control this afternoon. I set up an alignment stick about 20 feet out and hit 50 shots with my pitching wedge using short swings and slow enough to make sure I started the ball at the stick, either straight or with a tiny draw.
Later in the evening I hit 50 easy (50-75%) shots with my sand-wedge, normal awareness of hip-turn and balance, but focus on smooth transition and "letting the club do the work" as my dad says. I really like the ball striking with this drill. Maximum power with minimum effort, and very consistent ball flight.
