Current Cardano Parameters for Return on Stake

I’m trying to fill out the advanced parameters for the official Cardano Calculator as they currently are.

What are they? See screenshot below:

I’m currently not getting numbers that are matching a rough estimate about what I’m told the likely stake is. With Current Saturation of ( 64 million Ada * 5.5% ) / 73 = 48219.178082

What’s the current expected total return on stake for a pool operator for a fully saturated pool?
