Sorry I am confused

I thought that Sanctuaries were 40% and will remain 40%
But now I need 3 times more BBP to create a Sanctuary, so I expected 3 times less total number of Sanctuaries, and 3 Times more payout per Sanctuary.
1) Sancs always get half of the net reward - half goes to the heat miner and half to the sanc. The 40% figure was the amount a sanc would receive with 10% for governance, but now we have 48.5% for governance when including the GSC amount. But the sancs still get half of what is left.
2) You do get 3* the reward now for a sanctuary as compared to legacy sancs - this is a function of how many sancs are online (1/3rd), so the rewards are more frequent per sanc now that we only have 125 to pay.
