chrisironsbones: Usually irons will travel further with no spin than they do with full spin due to the roll out,
We've had this discussion before and you just can't properly map irons factoring in total distance. This is folly due to the myriad of landing places across all of the courses. (Filmslayer has a point.) Learning where your ball will actually land is way more important than trying to figure out how far it will go. That is why a fairway landing is a better gauge of the carry than landing on a green. Flat ground from start to end of carry is also important which is why those first 3 holes on the back of BPB work well-long, flat fairways.
The chart on your profile page is a beauty. I like to refer people to it because it shows this carry number if you read it correctly. The total distances are just subject to too many outside influences that you have to work them out for yourself. Learn where that rollout starting point is and then figure out what's going to happen.
p.s., Don't forget- the ball makes a huge difference.
