Fake dives grow my count

I have been using my G1 Solar just for a week, but there is something that bothers me:

when I jump into the water from a big boat, the dive starts on my Garmin but not on my Suunto (keeping both for the first week). Giant stride entry.

it seems all options are unsatisfactory: 

  1. delete the dive from the watch. If I do that, the count still goes up, and when I start my real dive it till be counted as the 2nd. This will make my dive count really different than my real dive count.
  2. try to keep the dive running. I don't know if I can, after 1-2 minutes it automatically closes it, but even then, it would be few minutes longer than reality. 

is there a way to REALLY delete a dive without increasing the total count? 

ps in case you wonder I'm in a group and I cannot control how quickly we start descending plus the Suunto doesn't do it, so please don't suggest a change in behaviour. It's a software issue.

thank you
