With all these measurement discussions, there is a level of resolution within which a material difference in results can be observed. Remember Sig Dig's? Significant digits- greater resolution adds no greater significance to the data. This is to say that measuring cartridge BTO length to within 0.0001" has no observable impact on results, just as measuring powder charge to within 1 granule has none, nor does calculating BC values to 0.0001.
I agree, there is a point where effort and reward are immeasurable.
But, do not abandon good practice, try to keep things tight, the reward is consistency.
With the tools available today there is less effort and greater reward than has been previously known.
I see this in group sizes shrinking and the probability of a hit increasing.
