I figured out the graphs for $18.77
there are 3 graphs because I played 111 $18.77 after the 500 block staked by vbzg (supavegi on Pokerstars)
first graph is from 26-feb till 29-feb
Second graph is from all the $18.77 played after that: total 217 games.
Since the last 111 games where for a different staker, we need to deduct those games:
If we add and deduct these numbers you will get the following:
331+65-563=-167
So I made a mistake with adding up the numbers before on the $18.77
The number that I stated before with a +$55 will stand however, since this is my own mistake!
This has been the result for $18.77 total!
