You can get two double CDP boni.
Precondition 1: Be sure to know when 12 am GMT is in your local time!
Precondition 2: Be sure to get the max CDP bonus of 880 XPs.
1) Play an 18 hole tournament until the last shots of hole 18,
2) save it.
3) come back shortly before the day change (12 am GMT) (or just play the tournament as the first of the day to get the bonus),
4) just before finishing, buy the Boost,
5) finish and get double XPs for the tournament (=800) + the strokes (=120+) + the CDP (1760),
6) relax and play what you want but leave a minute or two of the bonus,
7) in these last minutes, start another 18 holes tournament (be sure to stand on tee 1 at least)
8) save the game until the start of the next CDP day.
9) finish and get another 800+120+1760 XPs
The peeve is that you cannot play for 23 hours with a one hour boost.
Me thinks that all this trouble is not worth the points - you will get them easier and gratuitous in a few day's play.
