Also could have come from other side for posturing for the next one as this CBA is in its last season. Lots of reasons it could have leaked and guessing is kind of pointless.
This scoring system somewhat reminds me of how USSF assessments were explained to me. The "General Performance Metric" is your base score that every match starts with (75 or 81 or whatever) and then the KMI award the match difficulty. Every match is going to have a different number of potential KMI's.
