In a RL that data gained prior to the tourney is carried by the caddie in a notebook during the tourney. It's why a really wild shot will send players in to overdrive pacing things out and cussing at the caddie maybe.
Provided it does not lead to slow play, every shot, I personally do not have an issue with anyone using a generic shot calculator here.......... Basically I just don't think any of these generic fussy calculators get anyone past a low point "live" play wise.
All million miles away from walking around with a caddie called Mr Otto of course.
