that's probably the reason why i was diving 3 or 4 times a day during one week in Egypt with my Suunto
the algorithm in Suunto is Spencer + some RGBM, not a pure RGBM
Even a broken watch is right twice a day
I'm not going to argue with you what did or didn't do, or what your Suunto can or can't do. It's a known fact that the RGBM algorithm, or even a modified RGBM, that Suunto uses is ALOT more conservative than the DSAT algoritm that many others use, and will penalize you accordingly. Primarily DSAT is preferred, and used, when performing multiple, repetitive rec dives because of the liberal profiles the algorithm allows. Does this make it BETTER than a more conservative Suunto - absolutely NOT. Like I said, all a matter of preference. You can also make the Suunto computers, some of them, more liberal in their settings and get more time from them.
Suunto allows on some models the availability to tune the attenuation settings, as well as adjust the personal factors to manage the dive. But because they factor in the micro bubbles that DSAT does not, no matter how much you tweak the computer it is still going to be different - not better and not worse - just different because it gauges variables according to their models.
I personally don't dive my Suunto any longer. Yes, I could do the repetitive dives like you state, but the times were so minimal that it was extremely inconvenient for me.
There are different computers that do different things because the divers that wear them are just as varied in their demands.
If your Suunto can handle your diving style and needs, you enjoy diving it, it can keep up with you, and it keeps you safe, then by all means dive it and enjoy it.
Mine couldn't; so I either had to stop diving or get a new computer ..... Guess which choice I went with
And PS .... Just because you CAN do something, that doesn't always mean it's a good idea TO do it.
