My son and I both play WL. I play with a much better team (on paper) than him. Yet, I think he is a bit better than me.
During season my son was always S1/G3.
I always stopped at G3 with about 7 games remaining. During TOTS I kept going till G2, which I always achieved.
Last 3 weeks we held contact (son was at his mom's) and the win/loss ratio was about the same.
G3, G3, S2
Yesterday my son stopped at 10win out of 16.
I was 8/12.
This morning I started and went as follow
Now my son was 10/16 and just apped me he has 9 games to go, needing 5 wins for G2. Same as 12/21.
So you can call it coincidence, but if you are a G3/G2 player, the outcome is the same every week.
