Well i'll start with my personal opinion.
I would personally be ok with 40% and think anything above 51% seems like too much and I would like the photostars to have extra incentive to play from the hive rewards pool.
My estimation is that 40% at today's expectations would lead to at least 150 hive maybe more depending on how many hive users join C/photogames and play and how many "for fun games we do"
I could see that going up to 250 hive a week. But at 10% i think we'll be fine but the hive tips will be less of an incentive because it will go down to a much lower amount.
One day we'll have lots of players and perhaps we can turn on ads for the community and that revenue will go towards this as well.
Finally i think we can easily move the amount down or up pretty easily. It is not difficult.
I concur.
i don't really care 20-40% if the plan is to do X amount of seasons.
overall a lot depends on price of hive and autovotes on photostars :D
it is easy to change the % so maybe there should be a goal of X amount of hive in the pool and the % can be changed in range of 10 to 30-40.
