Here's some math that seems to be missing from the proposal post:
(numbers are accurate as of 1/23/23 3:53 AM EST, figured out live on SPLtv if anyone wants to check methodology you can watch the VOD)
SPS rewards 115,524,096.7 / year
Stake current 482,960,270
Stake if add 510,960,270
APR current 23.92 %
APR if add 22.60 %
APR diff 1.31 %
Just to shed some light on the issue for those who don't understand what effect this would have on the staking pool, and an additional note that the SPS staked in the DAO would be non-voting, therefore as players our effective voice would not be changed.
