*At 32m (for my guns velocity/height of scope - varies depending on setup)* your zero is minimally affected by environmental conditions and at all other ranges, you are dialing up (or holding over), never holding under or dialing down.
In the PRS game, where you zero doesn't really matter, because we are always shooting different distances and dialing or holding over from our zero for every shot. What matters is having a very accurate zero.
As a test, on 10 different days with varying weather conditions, take a previously zeroed 100m rifle and shoot 10 different groups without adjusting for the environment of that day. If zero day had a 5mph left to right wind, and the next day had a 2mph tail wind, and another had a 10mph 3/4 value wind, (and on and on) .. a 100m "zero" is going to be covering most of an 8.5"x11" piece of paper.
At 25-30m, no matter the condition you might shift 1/2" in any direction.
Its the same reason that in centerfire PRS, despite almost all targets being in the 300m-1000m ranges, we still zero our rifles almost exclusively at 100m

- all adjustments up, zero minimally affected by conditions.
More important to spend your time developing DOPE and learning wind to adjust for the further shots than to constantly have to modify your zero to fit the conditions of that particular day/hour/minute.
