Hope so, I do satisfy the criteria of being curious. Probably best to sight in zero at 100 yards rather than the usual 3 inches high at 100 yards, unless anyone thinks this is not a good idea.
In my experience, on baited leopard hunts the PH advises sighting-in at whatever range it is from the blind to the bait, which is usually 50 yards maximum. A sight-in 2" high at 100 yards will usually be dead-on around 35 yards, but it also depends on the specific ammunition and scope-height above the bore.
