Losing ranking point when winning?

Did you know you can lose ranking points if you win a StreetSoccer game only just so (meaning 3:2 or 4:1, instead of 5:0)?

Well I didn't... see here. I lost 4 points because I won 'only' 3:2. ( game)

That's because your expected score was over 60%

In other words:

Consider rating as indication of strength and the rating change as a correction to a previous indication...

You and your opponent have a big strenght difference according to rating.

But in fact you only got a 72 move draw and won due to the order of scoring, so your ratings should be closer to each other, leading to the 4 points 'correction' to your rating.

I know and understand the math and reasoning.

I just never saw that before, and it was surprising.
