What your describing is called "maximum point blank range" & you have described it accurately!
Its a very good way of setting up your rifle for short to meduim range hunting senario's.

ShootersCalculator.com | Point Blank Range Calculator
Calculates the maximum point blank range of a firearm cartridge fired from a rifle or handgun.www.shooterscalculator.com
This website illustrates my point exactly. You type in a 10" target and you get this:
Who in their right mind is going to zero 4" high at 100? Yeager is saying he wants his max trajectory ordinate to be 2" high (the 4" circle), which works. Four inches high at 100 means a lot of misses high at ranges you might be a bit rushed and unsteady (140-200).
On the other hand, the American Hunter link you supplied is great - if read to its end. Spomer explains exactly what I am talking about with respect to the assumption these calculators use, which is that bullets all travel in a straight line.
Spomer says reduce a 10 inch target to 8 or 6, which is exactly right if you want the max PBR. But I suspect most hunters/shooters on this site are dialing past 300 anyway (ie, not using the concept of MPBR). Hell, I once dialed for an ibex in Mongolia at 267 yards with a 7mm RM.
