I have my Edge alarm set to tell me when it's in the regen cycle. It went off yesterday and the event happened for about 8 miles. Low boost setting is at 3. I'm going to watch to see how many miles it is until this happens again. I believe it's been at least 350 miles since the last one.

Mine regens just about every tank it seems. It also seems to go exactly 20 minutes.

what is regen?

X2, and what happends when it REGENS?
