Okay, so once you get the hang of WILD wouldn't one basically have mastered it? I mean because its just a technique for example
wake after 6 hours of sleep so your in your REM
Get up use the restroom and read on DV
Go to bed, lay still and become relaxed
allow yourself to fall asleep while still being conscious
See your dream form, and enter it.

If WILD Is the same steps over an over it should be pretty easy to master once you get your first 2 WILDS and know when its easiest for you to preform it
