It has to do with how it scales. The higher you go the lesser the actual damage increases become. That is why the first charges makes the most impact to his damage. The percentage of increase is the most. So the actual damage increases the most.He has 621 rating on his own. The first charge increases it to 3921, in other words a 630% of the old rating.In order of charges those increase by, 184%, 145%, 131% compared to previous charge.So the amount it increases actually decreases per charge. And on top of that, the rating does not scale in a liniar fashion to actual damage.Hope I make sense.

His abilities specifically mention a numeric increase to crit damage rating by a fixed value, not a percentage increase to current value. In fact, I don't think any active buffs give percentage bonuses, although I might be wrong on that
