Improving or just a new crash and burn over 0.5 goals strategies?

I have been testing 2 new lay 0-0 strategies lately, both based on stats (goal scored and received by each team): first was tested on 3000 soccer games, and the second is a new one tested just on 351 games , and i want to see which one can give me more +1 goals in a row, so i started from 30.08.2015 till 08.09.2015 with the following results:
