Looks good. Can you explain to me the spikey revenues? Most days they are 0.

@steegecs The revenues are calculated using the WithdrawFunds function call on the EtherFiNode contract. This function can be either used to do a partial withdrawal (claim only the staking rewards) or a full withdrawal (complete withdrawal of principal amount plus the accumulated rewards). This huge spike in revenue is because we are also calculating the principal amount in full withdrawal as revenue. I have pushed a fix to remove the principal amount from the revenue calculation.
