Throw away the CTTH and Blitz they get very few experience points (XPs).
Tournaments set up in your CC get twice the XPs.
If I were you I would ask your CC if you could set up a week long Best of Par 5 unlimited play on the back 9 off the easy tees (red) at fast green speed for the next 3 weeks.
Here is the reason why:
The scores do not impact your average so you do not have to worry about your score.
You can play with cheap or free balls.
You get 190 XPs for a 9 hole round plus the 33 - 35 XPs for strokes plus the CC bonus of 5% from the CC level bonus for a total of 235 (apx) per round.
Once you get in the rhythm you can bang out 3 rounds an hour and still have time to get a beer in between every couple of rounds.
Between your CDP Bonus round and about 10 of those a day those 50,463 XPs will be 0 in about 15 - 16 days.

QUICK EDIT: Get there as fast as you can. The pop up says "through the end of November" once in the past they had the R-1 L98 driver at L 93 "through the end of August" BUT that did not end up being August 31st (the last day of August). It actually ended up being the 27th IIRC when they did an update.
So do not assume you have until November 31st and be safe and get there by the 21st if you can.
