conservative Mares?

[ClumsyCuttlefish]

I heard that Mares computers are conservative. But...sooo conservative?
I recently bought Mares Nemo Wide as my vision is low and this device has really large numbers. After a dive with a max depth of 20m (not the entire dive at this depth), 40 min, not exceeding deco limits and permitted accend rate, safety stop is done - my computer shows 9 hours of surface interval! Why???

I just got one yesterday myself. I found this while doing my research. Some good information. What personal factor did you have it set on?

Are you sure that isn't the surface interval to completely reset you to a surface pressure group? Or you're misreading it (90 minutes?)

To test that, I would take a reasonable SI (say 1 hour) and then do a shallow dive to 10m and see what the computer does.

I left all personal factors to be set up by default as the manuel recommends not to touch them unless you are some diving instructor (and I am not).

Yes, I am absolutely sure that it tells me hours, not minutes (the reading was 9:20).
I did not have opportunity yet to check its behaviour if I do not follow the recommended SI.
