I have the same clubs as you L75 bladez, I normally used 6 shots to get an idea of distance (3 up and 3 back down) and either ding or very close to ding. Neutral spin and fbs and then maybe 3/4 spin. To be honest I did this in more detail with a previous set of pings, then for this set I did a lot less as I could see a pattern set by the pings and you can refer to the ping yardage as reference if that makes sense.
Pick low wind, pay more attention to the length when the ball bounces, less important is roll after the landing, but make a note of that too. Kiawah one is good as well as the first few on the back 9 at BP.
I did mapping with L60 nike balls now I am using callaways and tend to just be aware how the ball plays different ie a bit longer and less bs and still refer a lot to the mapping I did with the nikes. eg if nike fbs 100% power goes 161 I know the cally will go around 162-3 yards carry.
Dont even get me started on winds, because if your estimate of wind impact on your yardage is off, it doesnt matter how well you have them mapped.
But, of course, having as accurate as possible base mapping is the best start.
