All is random, block was hit with less than 10THs.
The name of this race is LOTTERY so I pay for electricity about 50€ per mounth for lottery.
In winter I plug more miners for heating.

Your data suggests that people win the regular lottery more often. But now you can proudly call yourself a miner

10 TH/s × 100 days = 1,000 terahash-days
100 TH/s × 10 days = 1,000 terahash-days
The probability is the same, you can play for one month at $600, or you can play for 12 months at $50 each.
