I just did a lot of practice rounds and a lot of forum searches. Along with a bunch, and I mean a bunch of notes. I keep notes for each of my clubs from shots I have hit. For example: I write down the following:
64 Wedge (60y) 12y 1ft dwn 4 downleft wind / 25% = 11y.
25% is what percentage of the bar I hit and the result was 11y. I have tons of those for different clubs. When you get a few for different shots and lies it makes it easier to figure out what you need.
I am still new myself and this was my approach. Good luck my friend.

P.S. If you search for green speed yardage or some variation of that there are some great templates members have shared that will aid in distance control.
