Jim,
The tool is very easy to use and you're a plenty smart guy. If that's the number you're getting, I'm sure it's right.
The only other change to make is to measure the headspace of your own cases and adjust you're OAL versus the comparator.
Realize that the two fixed points are the case shoulder and the bullet ogive. Everything else is variable. You want an OAL that puts the ogive the same distance from the shoulder as it was in the comparator.
