They also have a 3 day discrepancy in surface interval which is really weird with teric #1 thinking I have been dry only 13 days, while teric #2 has the correct 16 day SI.
Twice I've had the Teric randomly reset the tissues. So that might have happened.
I've never been able to replicate it, it just happened. Once as I was getting out of water. And once just randomly while I was downloading my dives.
