Perfect answer, I couldn't have said it better myself

I am about as easy dive rec diver as you can get (for a NC diver). Dives 100 ft or less 95% of the time, within NDL 95% of the time. Within NDL of at least one computer 99.8% of the time. Dove a zoop + Aeris for several years and now have a zoop + Scubapro. After a couple hundred dives on the zoop I will have to agree with tbone. If I am being penalized I would like to know why. On one pair of dives the zoop will be pretty close to the scubapro on dive 2, on the second pair of dives it can differ by 10-15 minutes of NDL. I would like to know why. Is it a few minutes of SI? Is it a bit of a sawtooth profile. deck - bottom -back to deck - down in hold - back to deck - up to top deck. Whatever it is would be useful to know.
One thing I seem to have noticed is that the Zoop penalizes real slow initial ascents at least at first. Aeris and Scubapro will both be upping my NDL right away and the Zoop does not do it near as quickly.
I agree, Shearwater with gradient factors would be good because you can adjust them depending on the dive and conditions, who you are diving with etc. But most importantly it is not a bubble model programme like Suuntos RGBM which seems to leave you in the water longer than anything else, although of course you can adjust for conservatism on it. Not sure if the rec mode in Shearwater stop you from hurting yourself though, locks you out, beep and farts if you ascend too fast etc. It is really a technical diving computer in the first instance, adapted to the recreational market for obvious reasons. So quite pricey.@BurhanMuntasser I don't think I've gone off topic. Here's why.
OP asked for a non-conservative algorithm. What was required information that was not provided was whether he wanted a liberal algorithm for multiple rapid fire dives, or individual long dives. He did not mention what he wanted the computer to be liberal in relation to what he deems conservative. No mention of how liberal he actually wanted to go.
What I pointed out was that without a computer that you get to control the conservatism with a very simple to understand concept *i.e. gradient factors. In NDL diving you basically leave GF-Lo at default and setting the GF-Hi which allows you to choose the percentage of tissue loading that you want to dive with*. That to me gives me information that I want to know other than a proprietary algorithm with conservatism 1,2,3 but they don't actually tell you what those levels mean.
I trust my regulators to provide air, but there is no "magic" going on inside regulators. They are simple machines that provide a very basic function. My BC is a balloon with two valves on it, no magic going on. A decompression algorithm that does what Steve commented on by randomly padding the dive and not telling you why is performing magic that no one can understand because the manufacturer doesn't tell you what it is doing. That is putting blind faith into something that you have absolutely no control over and is the only piece of dive gear that we use that does that.
Regarding your comment about whether the OP asked how computers work. I think that's a bit harsh of a response since in order to understand what makes a conservative computer conservative, you have to understand how they work, don't you?
You want the least conservative computer on the market? Buy anything running a Buhlmann Algorithm that you can set the GF Hi to 99, or a VPM computer at 0 and since safety stops are optional, skip them. You are all but guaranteed to bend yourself running those algorithms in those settings, but there are many computers on the market that will let you do it. These computers do absolutely nothing other than track your tissue loading as accurately as they can. If you sawtooth profile, rapid ascent, short SIT, whatever, they don't care. They give you your actual dive profile in the log and you can see what you actually did. Why does this matter? Your risk of DCS is completely different diving in deep dark water kicking against a current in New England vs. a clear blue water drift dive in the Caribbean and the computers have no way to know what you're doing. As an educated diver, you should understand these changes and be able to adjust your conservatism accordingly.
Computers like Oceanic, Suunto, everyone running proprietary algorithms will randomly add conservatism and not tell you when they did, why they did, or how much they added. Just throw it in there because why not. That doesn't jive with me and I would rather run tables than use those computers, and did for a long time until I could afford a Shearwater.
Are you expecting the computer would give you an analysis report of your dive and details why it had the NDL it had? If you want a theory background on the computer and its RGBM, there are many documents and videos on the Suunto website and on youtube.
That to me gives me information that I want to know
