no, it really is "tightest"...

Lots of folks just shoot across a chronograph looking for the tightest numbers (lowest extreme spread)... and they go with that load if it seems accurate.

You can reduce ES after you find the OCW (optimal charge weight) for the powder.

I don't use a chronograph at the initial load development stage, except in certain rare circumstances.
