The .3v has been discussed numerous times and it's a tolerance thing with the components issued or something along those lines.
If you are bumding the alarm as you put it when you are doing stunts, #1 maybe the alarm is set to high #2 maybe the pack is not rated enough for your setup #3 maybe the pack is that great a condition. So many factors you can consider, delaying the telemetry is probably what most other users would want out of a live telemetry information.
my take on this is under load, the measured voltage will be much less than after you land.
I set my alarm to 3.3 and 3.4 volts per cell, but would get alarms way earlier than necessy.
I have since disabled this alarm, and instead fly my normal times and check the voltage after I land.
