3 Questions, 2 related to the above quoted parts: -1. If the conditions are met, then a delay is started, the conditions are no longer met, the event is suppressed, then the conditions are met again, and the delay time expires before they are not met, does the event occur? -2. What happens if you exceed 100k' with a previous version (1.4.1) of the firmware on a Telemega? There's a (very small) chance I'll be doing that next weekend, and after 2 months of trying to get my Telemega to work on 1.4 / 1.4.1 and finally having an acceptable flight today, I'm not going to risk updating to a new software version 6 days before launch. 3. Unrelatedly, what is the best way to set a backup main parachute deployment on a Telemega? I tried a parameter configuration today that seemed to make sense (I don't quite recall the configuration and haven't unpacked yet to pull it off the alt) and it didn't fire the match. Just want to see what's the recommended configuration, for say, channel C to fire a backup main at 4,000m?
