I don't know that you have to be "extra" concerned, it is still a modified Haldane model which have been used for decades in computers, and is based on the same model that creates the PADI tables. Those tables have inherent conservatism built in (they don't push limits for recreational purposes).
With that said, I would argue any time you come close to your deco limits, you should take extra precautions, Haldane, RGBM, tables, or computer, it doesn't matter. Slow ascents, deep stops, saftey stops, only serve to make all diving more conservative.

I love my 250.
And I have the same issue you do. It beeps a LOT on ascent.
I look at it this way. When do you get bent? On Ascent, right? If you stay at the bottom forever, you would never get bent, you'd die from something else first, probably like, no air.
But ascending is the part of diving where you can really get screwed up. If my computer makes me check my speed, more power to it. There is no harm in ascending at speeds slower than 30/ft min, unless of course your OOA or your buddy is, in which case the ascent alarm probably won't phase you anyways.
I was told by the LDS to increase sampling rate to keep the alarm in check, but after I thought about it for a while, I was kinda like "isn't being conservative in diving a GOOD thing?" I've just decided that if I have the air remaining to be conservative on ascent, I'll take the safe route.
Also - with me being a really new diver, I need all the help I can get. My dive buddy can calculate his ascent speed in his head for all intents and purposes, the kid is a genious, he probably doesn't even need a computer. He is so good at math he could probably do the NoDeco time stuff in his head as he swims around.
For people like me - for the love of God, beep at me, because I want to be safe, and I suck at math - lol.

IMO the ascent rate alarms are computers' best safety feature, especially for new divers. Most single tank, recreational divers are not going to push NDLs too much based on depth/time simply because a standard AL80 does not have the capacity to let them stay down that long. Of course, there are lots of exceptions, especially with repetitive diving, but in general if you respect recreational depths, take good surface intervals, and manage your profile intelligently, violating NDLs on a AL80 is not something most divers will encounter frequently. This is one reason that recreational computers can use widely varying algorithms and still be statistically as safe as the next.
Controlling ascent rate is another story; I see out of control ascents on recreational dives very frequently. Often it's new divers who have trouble controlling buoyancy at the end of a dive and blow a safety stop, or just start ascending and don't realize how quickly they're moving.

.....I traded away my Veo 250 that I bought as a back-up for my Oceanic DataMax Pro Plus II, a couple of years ago....for some strange reason, Oceanic saw fit to give the Veo 250 a different, more conservative, algorithm, from my primary computer...which really sucked....so this spring I used it as a trade in on a Cochran Gemini AI computer.....which tracks with my DataMax Pro Plus II quite nicely.

I have an Oceanic VT3 on my wrist and if I am ascending slowly, just bringing the computer from my waist to my face can cause the ascent indicator to jump up to the max.
This is one thing that I don't mind being to sensitive, it makes me improve my ascent control and go up verrrryyyyy slooowwwlly which is a good thing
ab-so-lutely

I got mine today. I dont understand what the bottom number (time?) on the display is?
Also is there anything I need to change on the second menu? (Im just running air)

The Veo 250 can be used in the Oceanic swiv console just fine. Even with the side button. The rubber boot is designed with an opening for it.
It's hardly conservative - in fact, compared to my wife's Mares Nemo Sport, I should be dead.
I don't have a problem with the ascent alarm - my Citizen Hyperaqualand alarm goes off sooner than the Veo would, and being on my wrist swings around more. So it keeps me from ever seeing 'too fast' on the Veo.
I would like to change to a wrist-mount, smaller system. The Veo 250 'user replaceable' battery is a bear to replace thanks to their door and 1/4 turn ring design...flooded my wife's that way, hence she has the newer computer. I'll have the dive shop do mine when it comes time this fall for a battery replacement.
Brandon: Any advice here is no replacement for READING THE MANUAL!!! That said, depending on what display you're on, the bottom number could be dive time so far or could be remaining ND time given current depth and saturation record.
