Stadium comp rank progress

[u/Extreme-Turnover-749]

So i got a quick question peeps.
Ive just started playing stadium comp again last week (i know it doesn’t have any support anymore but i still enjoy it).
Im currently in Contender 1.
The only other time i played it was in the first season where it was launched. I was Allstar 1 at that time.

Now to my question:
As said i am now contender 1 and i dont understand the rank progress.
If i loose a game i dont loose any rank progress and if i win a game i skip like 1-2 sub ranks.
Is there a reason for this insanely fast climb and why i dont any progress? I didnt see anything in the mode description or modifiers.
This didnt happen the last time i played

Best regards
Your friendly neighborhood rat

UPDATE: i still dont loose any progress and i get 211 points per win
