Two results don't prove or disprove your theory in my opinion.

I'd say to get an accurate base on it to see if there is any merit you would have to play the same team a lot more than twice. Probably up to 25/50 times each with and without bonus and calculate the average result from that to collate it into some form of data.

Freak results can often happen, trollings, injurys etc, while some players will play in form and out. To declare you have proof after trying just 2 games is a bit premature for me.
