JasCooper: Looking at Jesse's link he seems to infer that precision affects accuracy right or left of the mark and forgiveness relates to distance.
Both to both me thinks. Some analogy pictures say precision is the circle your balls will end up when hitting several perfect shots ("excellent", "ding"), and forgiveness is the area where shots end when missing the ding. Most of the latter shots will stay short and stray left or right...
JasCooper: Then, does elevation move that distance forward or backward along the arc that the ball travels. I.e. Higher elevation means shorter travel, and lower means farther travel. So drivers would have more variance. And iron/wedges decreasing amounts the greater the angle?
True, and here the trajectory has an effect. Good clubs may need the common "yards for feet" adjustment, low clubs like the Starters may need "club for some feet" adaption.
There are no official documents, but experience will get you along. Concerning "fade" and "draw", you may go just outside the next marks for acceptable results.
JasCooper: Now that my expensive balls wore out, I'm beginning to wonder if the balls costing a few hundred credits aren't worth the investment to get more distance, spin, and slower meter. Especially with clubs that don't have good meter speed or forgiveness.
Custom balls have a life of 100-120 shots (excluding putts from the greens), and get lost in water and OOB. Mulligans cost extra. You better balance the quality of balls and clubs because high priced balls are wasted with low clubs (No jugement on the COIN clubs available).
My two Pfennig: Try balls from low to high, e.g. B-ES, Tour-SD. Hold back Srixon, Callaway L33 and so forth for better clubs.
No difference in the value of "free" credits and bought credits, though they say that we get less ads when buying. When going the "free" way, players have to become used to the feeling of getting scammed though.
