Uhh, unless it's trash, paddles have a rubber surface. Add to that the angle of impact.
I just assume anybody arguing these points is joking around.
That includes trying to do something fancy *between* initial contact with the cb and the release of the cb from the tip. A continuation of an action, sure.
Then again, these fit perfectly with winning the lottery to save pool and other thread gems.
You do realize that period while short covers several MM of travel depending on the tip and the speed that you hit it???
Thinking you can/cannot do anything in that space has not been proven or disproved...
Until cameras are better and cheaper and there is enough money in pool to warrant real "in depth" testing any thoughts either way are opinion and conjecture.. Same thing with much of the "truths" about tips and shafts... Just because the water is still on the surface doesn't mean there are not currents at work underneath...
I know many of you think I am knocking the establishment but I am only pointing out a truth... For how many years were you told contact time was 1ms? It was close to a decade before the Russian vids showed up proving that it was tip dependent based on force and likely could extend to 4ms...
Not all of the science is settled because there is no money for testing.. Dr Dave, Bob Jewett, and Mike Page are working on no budget and as such not all tests will be adequate in depth or scope..
They do everything they can for the sport and I respect them for what they contribute but that does not keep me from voicing my opinion in the face of what I think is inadequate study and testing on some topics.... Especially when the discussions and observations from myself, players and cuemakers are in direct opposition...
We make our tips with certain COR and hardness readings because differences in those ratios make a tip feel, play and spin the cueball differently... How do I know those numbers/ratios matter? More hours of testing than you can imagine....
On tips and chalk I would bet I have as many hours in testing and research as anyone in the industry... That means that while I was not testing to publish I was testing to establish what mattered and what did not... If the interactions were as simple as many tests I have seen that were done to publish make out, my job would be a hella lot easier. It's not and it's getting harder as I continue to work on actual synthetic replacements for playing tips....
