Hi All,

I've GMC-320 rev. 4.25 (without wifi) and I discovered wrong average CPM on higher uptime.

Uptime is 52 days, 15 hours 38 minutes, it means:

(52days *24hours * 60minutes) + (15hours * 60minutes) + 38 minutes
= 75818 minutes.

Total count is 1944273

Average CPM = total_count / total_minutes = 1944273/75818 = 25.64

But the unit shows Average CPM 189.7 (it's nonsense).

I think it's a bug.

I don't get how they can even release all those faulty firmwares... This was fixed in 4.2 as far as I know.

GMC-300E+ V4.20 with sbt-11a alpha tube

My statements are "stuff-a-hobbyist-says" and not in any way professional.
