If a skilled iron sight shooter sees less than 10% advantage to adding a dot, then for those shooters the dot is 90+% pointless; plus you've shoved a piece of plastic between those irons you use so well, to catch glare/dirt/dust/moisture and snow.
The exception would be the competition shooter who is striving for any point/time advantage he can get. To them, 5-7% is a win or a loss- a huge deal. I shot with old Bullseye shooters in my youth and dabbled in IPSC when it was a thing. so I really get that.
If a guy wants to try a dot, hell yes go for it. I've got a scary accurate old Buckmark which, with irons will make my little spinner target dance at 50 yards. Maybe it's time to slap a dot on it and see if I can do it from 75.
