Here's a number most golfers have never seen: across 19,421 greens we've measured by GPS, the average green is 31.5 yards deep front to back — and the deepest tenth stretch past 39.7 yards.
If your irons are gapped ~12 yards apart, a 31.5-yard green is a two-club window. One number ("150 to the pin-ish") can't cover it. That's the whole reason rangefinders and GPS apps quote front / middle / back: with a front pin you land the shorter club; back pin, take more and swing easy.
You don't need to laser flags all day. A glance at three numbers before you pull a club — front, middle, back — removes the guesswork. Caddie Tap puts them on your wrist for every green on 1,140 mapped courses, measured the same way as the data in this article.

Because a 31.5-yard-deep green means the front and back numbers differ by a full club or more. Playing to 'the middle number' with a back pin leaves you a long lag putt every time.
You'll average out — literally. Front pins will see you long, back pins short. Matching the number (front/middle/back) to the pin position is the cheapest accuracy upgrade in golf.
