The exact quote is "Unless you have a glaring weakness or a facet of your game which far outshines the others, you should spend 65% of your time practicing the full swing, 20% of your time practicing the short game, and 15% of your time practicing putting."

If your short game is a glaring weakness, then work on it until you feel or data from GameGolf shows it isn't a glaring weakness anymore. 

Some of the worst PGA tour players proximity to the hole from 20-30 yds is 13-14 feet. https://www.pgatour.com/stats/stat.380.html

You as a 6.7 hcp amateur putting it to 20 feet from 40 yards out isnt all that bad of a shot. 

For reference, I'm a 10 hcp. According to GameGolf, from 25-50yds, I get 39% of my shots to within 15 feet. That means 61% of them are greater than 15 feet away, and I dont consider my short game to be a glaring weakness. Its not one of my strengths, but not a glaring weakness either.

I don't know that if is the short game @klineka, or full swing or what. Toward the end of the 2017 season here in Upstate New York (so like October/November). I was struggling with "full wedges". I have an issue when I can miss the green completely from 75 yards. A 60° wedge for most of us... I was having issues with hitting these shots that were either fat, or I'd take no divot and the ball would end up short of the green... I think a lot of it was this over the top move I had... Craig and I have really worked to get my path to the point that I'm comfortable with. Though I am at like 340 days in a row on the Practice Challenge, most of my work has been on rebuilding my full swing... I am really trying hard to A) Try to be eligible for the State Mid-Am next or maybe this year. B) Possibly be on the Newport Cup team in 2019 (Yeah right, @iacas would never select a cook as his number #6)... I mean I'd love to make the team... the only "team" I was the best at what I'm doing was the "Quiz Bowl" team. I am a plethora of useless knowledge, and I can tell you the date for any date ever in a few seconds.

How does one figure out distances on short shots?  Driving range balls are dead compared to regular golf balls.  From my experience at the courses I frequent, on one course the range balls seem about 10% less lively, and on the other course, the range balls seem about 20% less lively.  Of course, those are just guesses, but the fact is, I don't think range balls can be used to calibrate distances with various clubs. 

So how do you intend to figure out the distances with these half shots you need to execute?

I don't use range balls, I use my shag bag on our practice area at my home course. Maybe I need to practice this more.
