OP was obviously using the ! as a factorial.

Seems pretty self-explanatory. Can't see how there was any confusion.
Are you referring to the max amount of prestige you can get per battle? It's been 500 since the change happened. It used to be 1000.
EDIT: Actually, scratch that, it looks like it was changed back! You get 1000 prestige per battle now (assuming your CP is half of that of the defender's). Time to go train some gyms.
Sorry I was pretty excited.
I was just battling in a friendly against a 1912 arcanine with my 1088 marowak, ran immediately after winning, and was awarded 878 prestige points.
Floor ((1912/1088) * 500) = 878
Yes, it has changed. The 500 I referred to was the multiplier, not the max. The max (at least in that battle, and the battles I did after) went back to 1000. I believe the multiplier has changed from 250 back to 500.
I'm located in the SF Bay Area. The change took place for my wife and I in the middle of leveling up a gym. First few battles yielded small prestige gains, then suddenly it changed back.
It was getting old having mostly level 3 (and a few level 7) gyms all around town. All the "vacant" gym spots represented wasted capacity and less availability, especially for lower level players. I didn't like the stagnant towers but this seems like a better balance.
This is a good thing, but it's still gonna be pretty out of whack. It may inspire people to put better pokes in gyms, which may inspire people level up such gyms and put better pokes in it. It's not glory glory hallelujah, but at least right direction.
Still don't know why they just don't make bubblestrat go away.
