Are you not over-analyzing this? Hundreds of people dive every day in Cozumel using all different kinds of computers, including Suunto. I recall your other thread from a few days ago, and I refrained from commenting because I didn't think I had anything to add (and I still don't, but since when does that stop people?).
What is your actual concern behind these threads? Are you: (a) concerned about DCS in Cozumel, or (b) concerned your computer annoyingly will go into emergency deco? If it's (a), do you have reason to believe there is a higher incidence of DCS in Cozumel than other popular dive regions? If so, please share the information--and I'm not being snarky here, as I really am curious since I dive in Coz occasionally. If this is a valid concern, then there may be a larger problem with Coz dive ops than what computer one uses. And yes, the surface interval stats would be interesting. If there is some reason to believe that dive ops in Coz are not following as conservative practices as dive ops elsewhere in the world and that's leading to a higher incidence of DCS, then that would be interesting to know. A possible way to deal with it would be to emphasize to your dive op that you are a relatively conservative diver and outline what you expect the dive profile to be like. Pick one of the dive ops that people here on SB have recommended again and again. SB is a great resource for that. But this doesn't really have anything to do with what computer one uses.
On the other hand, if your concern is not (a) but rather only (b), it seems to me that you just don't like your Suunto, and your "problem" would be solved by buying a different computer. I have a Suunto D6 and my dive buddy (wife) has a Suunto Cobra 3, and we like them very much. I KNOW Suunto is more conservative than many other computers, and that's the primary reason I went with Suunto rather than another computer. On rare occasion, this has led to us ending our dive earlier than others in our group. When it happened, we saw it as insurance and an indication that it was probably just as well to call it quits for the day and have a margarita. To agonize over your Cozumel trip simply because, at the root of it all you don't like your computer seems like an exercise in frustration. Just get a different computer and acknowledge that you're not as conservative a diver as you thought you were when you bought the Suunto.
Lorenzoid,
If you read my posts in the other thread, I was pretty clear about why I was concerned.
Since this will be my first trip diving in Cozumel, I am not familiar with the dive sites, but I did get the impression from reading trip reports that there are swim throughs at depths, possible downcurrents as well as strong surface currents.
I found it concerning in many many of these trip reports, people with Suunto's described problems doing the the two tank dive profiles - either going into unplanned deco or having to ascend early and separate from the group.
I think it's totally reasonable to ask why this might be happening so I asked for people to share their own experiences so I could get some insight into how to avoid what was, in my opinion, a bad dive plan.
There were lots of responses that I found helpful - others not so much usually because they made some incorrect assumptions or they chose to go off topic.
I chose not to take offense but it was disturbing when these posters started putting words into my mouth - kind of like this one.
I have never said I am concerned about DCS in Cozumel - I am concerned about DCS because I choose to do recreational diving as a hobby.
And yes, you are being snarky, because you are posting with the tone that you have tried to refrain - but you just can't now since I am being so unreasonable.
You admit that a poll on surface interval stats would be interesting - my curiosity stemmed from some very strong opinions voiced on the other thread so I thought it would be an interesting exercise if we actually polled the SI times based on hard data - ie. looking in your logbook (or software) - rather than recall that they went with a dive op that said they had a 60 minute SI policy.
And yes, I picked a dive op that has been recommended again and again by SB - something I have stated many times in that thread.
As well, I have also made it very clear that I am totally happy with my choice of dive op and that I am confident I can dive safely in Cozumel in that thread.
I also made it very clear on that thread that I had done many dives with my Suunto using Nitrox without any issues, but because the MOD of some of the 1st dive sites in Cozumel exceeded the EAN that is available, I was asking what other people did and I got my answer - air for the 1st dive and Nitrox for the 2nd - and I also stated in that thread that I am good with that.
So I don't understand why - when I have also been very clear in my original post on the purpose of this thread - you feel there is any value to a post in this thread going into some long diatribe about my "actual" concerns in my other thread.
I am not agonizing over my Cozumel trip - rather I am quite enjoying all the new diving concepts I am learning - thanks again for those more experienced who took the time to share your knowledge - and hopefully others reading the thread can gain something that is useful for them as well.
I believe good planning and preparation is part of our Basic Open Water training so I don't know why you feel the need to be so critical -maybe I should over-analyze your motives for your post - now that would be a waste of my time.
k: for that last line
