GAC banner bug costing two wins

I know there's a post about it, but in competitive Kyber 1 every single banner counts. I've lost the past two of my GAC matches because the banner math isn't adding up properly.

You could argue that it happens for both sides so it's applied "fairly", but when you're trying to calculate what you need to use in order to win, it's very frustrating not to actually knowing that.

I don't really care about the crystals lost, but more so about the hit to my Skill Rating.
