I'm just a rec diver but love my Predator. Why is the choice of 'last stop' 10' or 20' ? I have been advised to set it at 10' I know that this is in the 'deco' part of 'system set up' but why not have a choice at 15' ?

More realistically, you can set it for 10' and sit at 15'. As a rec diver, it really will never make any time difference at all whether you're at 10' or 15' for that last stop.
LMAO...it was you who advised me to set it at 10' but I wondered why. Tried several times to meet up at FB as you suggested.....had the feeling I was bothering you too much with many 'basic' questions.
It doesn't matter what you set it at as along as you have NDL time remaining as it won't be used anyway.
Imagine the scene:
Recreational diver makes 250 dives using a recreational computer and occasionally entered a bit of deco. Perhaps the diver had a minute or two minutes here, and couple minutes here, no big deal. This same diver purchases a Shearwater and excited about the ability to program a bunch of gases, programs and makes active 21, 32, 36, 50 & 99% because they've heard of those mixes. This diver grabs his new recreational sidemount kit (just sparking some thread interest, could be a big steel) and makes a dive riding the computer. Sure enough as before, a couple minutes of deco accumulates. No worries, we'll ascend, complete the deco, and surface. Upon ascent, OC 21/00 suspisciously turns a yellow color, and our hapless diver thinks, huh never seen that before. Reassured by previous untrained deco adventures the diver thinks, I will follow the computer and make a stop at 20ft for :10 minutes. After the diver completes :10 minutes of deco, :07 minutes are still remaining on the computer. The diver double checks available gas and he's now overdue for the dive boat, but the decompression time just is counting down properly. The diver is very confused and eventually runs low on gas and maybe even omits deco. Shearwater says "CONFIRM' and that's the end of it.
While the Shearwater products are very easy to use, there is a risk is changing factory settings if you don't understand the information you're being provided. The above scenario is something you could very easily fix underwater, but like the 10ft vs. 20ft stop as a recreational diver it really shouldn't matter.
Cocoajoe, were you referring to me? If so, I haven't been ignoring you intentionally but FB isn't something I understand all that well with the new features/settings/message restrictions...feel free to PM me on here.
