Calculation error in reward distribution of staked atoms.

[arunmadan101]

Describe the bug APR is 15.5%. But I have received 15 pAtoms as rewards for staking 500 sAtoms in one day

To Reproduce Steps to reproduce the behaviour:

1. Go to https://gala.pstake.finance/
2. Convert atom to pAtom
3. Stake pAtom and convert it to sAtom
4. Wait for one day and check the rewards recieved.

Expected behaviour Per day reward for staking 500 atom must be around 0.21 pAtom

as mentioned in the documentation, the gala environment is a simulation of the actual cosmos pos environment with the unstaking period, inflation period, epoch interval etc. altered. unstaking period happens to be 21 hours, instead of 21 days. similarly inflation period happens to be 15 days instead of 365 days.. which means 15.5% apr applies not for the whole year but for the span of 15 days.
