@philipma1957 I have to apologize. Honestly, I didn't understand these accounts very well.

What you propose is to check the average number of blocks that each pool found? And then understand if there is a difference between some days and other days? And that?
Isn't it easier to evaluate the hash that each pool has applied?

not with foundry they do not show their hash gui as far as I know.
but you can find the blocks they make.
when we dropped all the blocks off the pace they were off the pace.
does it mean they did a down clock no.
it means they may have downclocked.
and when they make 15 blocks in a time period that they should have made 23 it slows the whole net work.
which in turn clogs the pool.
but proof that it is on purpose to pad their fees is very very very hard to do.
