I posted this in the Induction Techniques sub-forum, but I didn't get any answers

What alarms should I set to practice DEILD at night?
I'm using the Easy MP3 Alarm Clock on my computer for my DEILD alarm.
If I do a WBTB 5 hours and 50 minutes after falling asleep the first time, when should I set my alarm for DEILD attempts in between?

For example: I go to sleep at 9 p.m., and wake up at 2:50 a.m. to do a WBTB. At what times would I set the alarms (in the middle of going to sleep and waking up for a WBTB) to DEILD?

Thanks in advance!
