Calculating Resting Heart Rate

I've done it both ways and find it can be vastly different. When I think about it, it goes up. I usually put my HRM on my wrist at bedtime and put my strape on when I get up in the middle of the night and start it when I first wake up.

Seriously you want it as low as possible, so see which works best for you. I'm looking for my first morning reading in the 30's...maybe this year?

however you choose to record it, do it the same way every day.  consistency is what you are looking for, not necessairly the lowest number possible.  by doing it the same way every day, you will be able to see any fluctuations that may signal overtraining or an oncoming illness.

Actually, you do want the lowest reading.  If you're recording anything higher, that's not your resting heart rate.

i suppose if you want to be able to say that you have XX as a RHR or to use it in some zone calculations, yes, you would want the lowest.

if you are tracking it for use in seeing how well you are or not recovering, doing it in a consistant manner will be fine.
