I have noticed that my OSTC 4, #474 with 1.3.9 must have a software bug.
A dive with a surface interval of up to 24 hours always has some CNS value between 300 - 900%! The way I dive usully gives a CNS value between 15 - 25%. But the OSTC only gives normal values after a >24h dive break.
Am I alone with it?
I also see strange values sometimes however not every time. Last dive I can find is from late december where I did 2 dives; dive 1 ended in CNS 13, where dive 2 started with a CNS of 347 and after 26 seconds it went back to 3.
That's exactly what I've been noticing. Always with a 2nd dive with a distance of less than 24h from the previous one the CNS values at the beginning of several 100% are not correct at all. Each time the CNS value of the 2nd dive comes to a normal value after a time of 20-30 seconds.
People, please check the CNS value output by the OSTC4 at the beginning of each repetitiv dive with surface interval less then 24h. We are hardly the only ones!
Checking again and indeed....
Last October I had a week of diving with multiple dives, there's however something strange, since the very first dive in the sequence also begins high despite having an interval of about a week:
23-09-18 CNS start 0, end 7
01-10-18 CNS start 215, after 26 seconds 2, end 16
01-10-18 CNS start 999, after 26 seconds 16, end 30
02-10-18 CNS start 52, after 26 seconds 0, end 2
03-10-18 CNS start 0, end 11
03-10-18 CNS start 249, after 26 seconds 2, end 15
04-10-18 CNS start 477, after 26 seconds 4, end 16
04-10-18 CNS start 476, after 26 seconds 4, end 17
05-10-18 no CNS information available
Also on 24-10-18 after an interval of 10 days, it starts with 608 and after 26 seconds it's 6 and 10 at the end of dive.
All above information is from the Diving Log application into which I directly import my dive computer.
