Just from the math there is a huge difference between 72 out of 75 and perfect score (like running 75 in straight pool or running 75 in 4 innings).
So the chances to get a perfect score in both are astronomically little. With 90% to draw perfect target each shot its 0.6% (one in 133) to get the right position 48 times in a row.
And for most people (including myself) 90% is way too optimistic (at least at the moment). On most draws I am more like 60-75%.
So I did mean it as a bet. Getting some favorable interesting odds (as an idea). I would bet $ 100-200 of my own money to win potentially a few thousand. Neither sum would be a life changing amount but the bet would add to the motivation to find out, how close I can get.
This was the reason for my post.
As for your question of how much I would offer for a perfect score:
I could imagine to match your offer

Something in the range of $500 - $2500 sounds interesting. (So that I could win something myself.) This way I would have a chance to win 50% of the prize pool and have a motivation to stay on the challenge.
If we make it AZB only then it would basically be a challenge between us two and perhaps Poolmanis (and potentially a handful others). With the knowledge, that in about 98% nobody will have a perfect score but the potential prize money could fuel lots of practice sessions trying to find out what is possible.
So I would match your contribution to a best total AZB score (or everyone under 720 Fargo to keep Bongers, Filler and SVB and the likes out) in both drills (say "have to exceed 180 points out of 200 and gets paid). Say something like $200-1000. And a bonus for perfect score (range $500-2500).
And we could do it in the same manner just for the follow drill (we post the same amount each for the perfect score and the first one getting 100 gets the prize, while the challenge also stays open to AZB and the participants that have already contributed to the challenge.
