48 hours solo I dug 8+7 = 15block * 7,67xpm = 115XPM / 2day = 57XPM/day
24 hours on the Ypool I found 8 blocks received only 43XPM -- This is 42% less than it should be
Over the next 24 hours on Ypool I found 10 blocks and got 59XPM
Subtotal:
48 hours solo - 15 blocks 115XPM
48 hours Ypool- 18 blocks 102XPM -- This is 35% less than it should be
Hence it can be assumed that the pool just stealing 30-40%, and at the original commission of 10% is obtained that the pool itself takes 50% of all coins.
