The calculation will be as follows: APR = (Av 7day perf fees pool annualized + total annual farming reward) / (total staked)
As the total annualized reward is 10,000,000 UBXT for the "UBXT staking" pool, considering that the perf fees pool is not yet opened, if the sum of the staked amount is 20,000,000 UBXT, this will represent an APR of 50%.
