[Shards]

This is mainly reliant on consistency and confidence. When confidence is max they are on a hot streak and this gives a boost. The boost amount is determined by consistency. The lower consistency is the larger the effect of high or low confidence.

I was also thinking that it would actually show the ratings changes somewhere but this is better in my opinion. Now you know what a players base is and if he's on a streak so you can determine gameplan from there.
