Not sure how you got the number of dives this year but I know that even without the dive manager from the history in the computer it say 138 hours 211 dives.
This gives an average of about 40 mins but thats not very comparable since its swayed quit a bit by the short dives done whilst divemastering on ow coarses.

Ah yes, I have just tried that and it works, it exports the dive time in seconds though so you have to work the numbers a little.
It works out as an average of 60 mins over the last 50 dives which sound a lot more sensible to me!
You can also export the full profile data (which is a lot of data!) unfortunately excel crashed when I tried to do anything constructive with it (surprise surprise eh?).
