It's only really an issue at close ranges when getting waaaaaay too precise at 25. Past that, 1/10 of an inch won't make much difference, but it's always better to use the most technically correct data if only to maintain credibility.

A PEQ15 has a distinctly different offset profile. I use 10-meter laser boresight targets and shoot at 25, 100, and 200 meters, with a 200 meter preferred zero.

I also prefer to work in meters, so at the bottom of the JBM calculator I click the "Ranges in Meters" box.
