It's a bit confusing exactly how they are calculated. KMI is the new measurement index for stores, but we were promised it wasn't used to calculate pay related things. Second, ETL bonuses were also scaled based on pay grade (and review score). An ETL at the best store ever who was a PG13 and an EX received a much larger bonus than a PG9 ETL who got an E in the same store. Paygrades went away so now the bonuses have averaged out so those bigger ones don't exist. There are now also only 3 scores for reviews instead of 5, so it removes those large multipliers.
