Over the life time of an engine, sure.  I think we are saying the same
thing here, that BLM is for correction, not tuning.

Why would efficiency change dramatically at a cell boundary?

I imagine that a cam going flat would really lose efficiency at higher
RPMs, but are we going to keep running an engine with a flat cam?  Are
we going to tune to that condition?

And why did they also use so few?  Anyway, not a question for me to try
and answer....

I have seen cell blocks duplicated for CannPurge and non-CanPurge
operation.  You would really have to know the problem that the code
writer was trying to solve.
