PTR SR massive change!

Hello, I wanted to know why I get 100 sr per win in the PTR and losing 100.
I am diamond rn and that feels stupid that I can get to master with 4 games win streak.

Because the PTR has very little data to base your SR off of, therefore the standard deviation is high. Look up ELO calculations if you want a more in depth explanation on the math behind it, but it makes sense. The more you play the lower the standard deviation will get and the less SR will swing.

I’ll be top500 on PTR soon mark my words
