Sorry - not really new, but the discussion may help others.
I am sure others here (including me) use this, or a very similar method. I do a combination of mapping and recording results for each key shot on each hole of each course. This gives me insight into how each hole plays and gives me more general input on adjusting the mapping. I record all this since my memory is not as good as it used to be, since my brain storage is pretty much maxed out on more important stuff!
I then use previous maps, with this data and a very skeleton mapping of new equipment or balls to start the new cycle of recording and adjusting.
Rinse and repeat.
This came out a little harsher than I intended. Your "discovery" is important and probably useful to quite a number of people looking for ways to accomplish this.
It is all quite complex. but is fun for me to attack (and I think the same is true for you).
