It'd be hard to convince me that 3" high at 100 yards is EVER good. If it's a far shot... you'll hold high... everytime... almost regardless of your 'zero' distance... it's instinct. Plus, most folks shoot high under pressure anyway (buck fever, yanking on the trigger, shooting off 'hard' rests, etc.)... couple that with the 3-5" high at 150... and you get a lot of critters escaping unharmed... that should have been next to the mashed potatoes. Been there, done that...

To rear children in an atmosphere of love, security, and faith is the most rewarding of all challenges. The good results from such efforts becomes life's most satisfying compensation. ~Gordon B. Hinckley
