I am pretty sure it was meant as a harmless joke but I can see, how you could get offended. Perhaps it didn't help the overall discussion.

apart from this I definitely see more personal and aggressive statements from your site. And didn't notice dr_dave putting anyone down. He just tries to adress every comment which is very time intensive so his answers get short sometimes providing links to the work he did put together already. But this thread really wasn't meant to get personal and have this much room for escalation.
Most scientists don't claim to be perfect. You just have a theory and try to back it up with experiments. At the end: let the cue do the talking. If you can come up with better experiments, you are welcome to do so and post them here.
Lot's of people believed (me included), that you need softer tip for extreme english (side or bottom). dr_dave had a theory, that it doesn't have to be true and could back it up with a video. Claim by Lou, that he was cheating using a juiced CB seems ridiculous giving the fact that I had same result on my equipment on my first try with a shaft and tip I never used before.
Lou prefers softer tip, Alex Pagulayan prefers softer tip for one pocket, I prefer softer tip.
At the end of the day: use whatever works for you. I found it helpful to know, that you can achieve very comparable results (slow sidespin, fast sidespin, draw, masse) no matter what kind of tip you are using. And I think this was the main message dr_dave tried to get into the pool world.
