Maybe but there shouldn't be that sort of rpm drop on the two cylinders with the biggest positive compensation when the other three are all negative compensation.

Look at the compensation on #1 - max -1.38 and on #3 +1.79. Get your calculator out because that's about 3.2% difference and #3 is still slower by about 30rpm so something isn't right somewhere.

Also don't forget that is an absolute limit and not a target, if the two cylinders that had the biggest positive compensation were running at the same speed then maybe it would be acceptable, however they are the two slowest cylinders.
If all injectors were on negative or positive compensation and all running at the same speed then the +/-2.3% might be ok but it's not getting the speed despite the compensation.
