well if you 2 table you do 200 hands per hour = about 4.8 BB rake per hour if you are platin I gues you get like 23% RB (rough estimation)

so your true winrate is 1.21 + 4.8*0.23 = 2.3 BB/hour = about 14$ per hour

but if you 6 to 8 table and dont win anything in the long run you get supernova easy (and some steps to elite).
= 27% RB and about 600 hands per hour
true winrate = 600*2.4/100*0.27 = 3.9 BB/hour = 23.5$
