I have to say that I admire you for wanting to improve things, and I agree with most of the points you've made in this thread, but let's not act as if this thread were called "What do you think of this possible nine ball break rule?" No, the thread was called "fixing the game of nine ball" You stated that nine ball is broken and the break is the reason. You stated this as it were indisputable fact rather than a matter of opinion. Hence, you are the one that prompted many to focus on the validity, or lack thereof, of this assertion.
Put me in the group of those who feel nine ball is not broken and that it is evolving in a desirable way, although I agree with nearly all your views on the need to keep the game moving at a good pace.
At Large's stats show that, at the elite pro level, with the three point rule and the money ball on the spot, the breaker usually wins between 55% and 60% of the racks (assuming a nine foot table). I don't have a problem with the breaker having this relatively small edge in a given rack.
The long packages that I always read about on this forum never seem to happen when I'm attending a tournament or watching on stream. I've been attending nine ball tournaments live for over forty years and watching streamed pool for many years, too, and I can count the number of 5-packs or more I've ever seen on my fingers. Did you know that at the 2020 Mosconi Cup, Team USA won less than 50% of the nine ball racks in which it broke? On tough equipment, the break guarantees nothing. If the equipment befits elite players, only straight shooting and good decision making get one to the finish line, not, as some suggest, the constant presence of dog-proof layouts.
You bring a very well informed view to the forum, but so do many others.
