I don't bother with the subtraction. Just measure the maximum outside spread but then I'm not worried about impressing anyone with my size... .
The shot that really matters is the first cold bore shot anyhow but I like to use two rapid follow up shots.
In the field the first is the most critical and you'll rarely get an opportunity for more than two follow up shots.
If you can maintain sub MOA accuracy with the first cold bore shot always being repeatable you have a reliable weapon to hunt with.
Yep it's cool to see just how tight you can get a 3-5 shot group letting the weapon cool down in between etc but I'm a hunter and predator controller so I approach it differently than a target shooter.
