Rule 1) always fly upwind. The only exception is when you just take off and you know you are good for X minutes of flying, I will fly downwind for 1/3 of X minutes and the remainder 2/3 I will fly upwind.

Rule 2) LAND is 3.5V/Cell. on a 4S pack am ON THE GROUND at 14V
Rule 3) Provided you obey rule1 and 2, "turn-back" Voltage is 3.75V/Cell or 15V on a 4S pack. I find I can always make it back safely at this voltage. If I get back and have juice to spare, the option is either land if I dont feel like flying anymore, or loiter until I get to 3.5V/Cell

Following the above "rules", I have never had a problem with being safely on the ground with juice to spare.

yeah like I say i go by voltage only. And that works if you know your lipos well like you do. Also I don't know how much to trust Amps/mah meters.

I mostly use Nanotechs and ZippyCompacts. They will have discharge voltage to work with your system

But there are some tricky high end lipos out that which could cause real trouble using a voltage program like you describe. The TBS batteries are known to hold high voltage for most of their discharge, then they fall precipitously just near the end. That would make it difficult to do a long range flight, since you woulnd't really know when you were at your remaining capacity for safe return.

i guess you just get used to it eventually

Yes, I would have to agree with the idea that you must "know your batteries"
