Everyone should do this if they're going to hunt at any varying ranges. Some only can see 40-50 yards max where they hunt, so the POI won't change much but those who don't, they MUST know where the load hits at every range.
Additionally, they should take shots at all the ranges using the position/rest they will be using in the stand. Shooting 150 on a bench is A LOT different than shooting off your knee at 150. Most would probably be quite surprised with the results.
