If you're still feeding the GP then you can definitely go more than that.. I tend to feed my fish (using NLS, GP, Omega, among others given out via breeders) anywhere from 8 to 12+ pellets a day (depending upon size and fed multiple times a day) with no health issues/bloating/constipation. My females especially tend to have pretty good size rounded bellies, my males slightly rounded.
But your GP size, I'd personally would toss in 3-5 per meal twice a day and see how he does.. work him up a bit slowly at first and see how he handles more food.. if he shows a healthy rounded belly after 8 pellets total a day then stop at that.. but if he is active and his waste is normal then continue up to 10 if you would like.
Your using the GP 500-800 micron, correct? This is the 500-800 next to a quarter.. so definitely.. 3-5 per meal twice a day is fine.
Some people feed more, some less.. if he isn't as active then may want to look at other things to, such as temp of tank, how much mental stimulation does he have (decorations/plants), etc.. bettas can do fine and be active with as little as a couple pellets every other day or so.. but generally they are a bit more active the better they eat.
This is my opinion.. I know many breeders and big hobbyists tend to feed quite a bit more than what is recommended on here, but it's at your discretion on how much you want to feed a day, what you are comfortable with. 5 a day is also just fine to feed, as long as it's quality food.
