These are just some thoughts from someone who feels they're 'being promoted too quickly through the tiers'.
Joined earlier this year, but had a hiatus imposed by work. Still, progressed rapidly through Hack and Am, arriving at Pro in almost no time. Bought some better clubs, and started hammering on CTTH challenges because they looked like the best alternative to a driving range. And they've been hugely helpful for me ... shots are starting to feel like a reasonable exercise I can play with successfully.
Then came a weekly 9-hole unlimited play, and checked up when I saw that my Hia back 9 scores were dropping my average quickly -- too quickly, for my liking.
I'm not going master until i'm ready (if that happens). Next tack for me is to start on harder loops, and let my average go the way it goes. If I go over (well, under) the threshold to Master, then so be it, but it'll only happen when I do it on the toughest sets.
I wonder whether too many others aren't tempted to turn in the top-notch cards, then flip out when the tier upgrade stuns them. I'm gonna sit back for a bit and get comfy at pro, while watching my average and making sure I don't get myself in over my head. If that's thought of as sandbagging, then so be it ... in my mind, it's merely intelligent progression.
Might the answer not be a walkthrough? Stickied?
"If you wanna get to master in 9 hours, here's how, but this is how it's gonna bite you in the butt!!!!!
And go from there ...
