Payouts amount unregularity?

Ok, here is my zksync payout over 5 months. How to explain this?

1 node full, 10tb used / 7,5 TBM
other node growing or stagnating TBM off as everywhere.

It should be Around 30 storj! or 21$ or am i wrong?

I can not find an explanation, TBM not matching, Storj Token price? it does also not fit.
On L1 it propably noone noticed similar things, because of high fees.

Does that payout differ from what you see on your node (the “Payout Information” screen)?

no.
it declined 2 dollar in feb. but there was no jump-growth to explain this going up … wait, its the egress. it was hight last month.
may it be the free user cleaning? and declined because of that, then goes up because egress. sounds right.
