Them 21seconds also include the traveling time if you look at the dive if you have done for 30ft/min ascent then 10ft is 20 seconds.Thanks @KenGordon
This is very interesting. So....I reran the 4 profiles from post #21, that used stop times of 1 min, by using stop times of 1 second. The results are significantly different:

16 minute dive to 100 feet on air:

So, there is still a very short amount of stop time when the GF lo is decreased, but it appears considerably less when 1 second stops times are used rather than 1 minute stop times. How does the dive computer deal with this? What does the computer use for stop times? My only Buhlmann computer, a Nitek Q, displays stop times in whole minutes. Are these actually whole minutes or are they fractions of a minute like planning with 1 second stops? In plan mode, the Nitek Q gives the same NDL regardless of the GF lo setting, only dependent on the mix and depth and dictated by the GF hi. GF lo does not kick in unless you exceed deco and cannot directly surface under the GF hi
As long as you ascend at 30ft/min you are going to have 3 seconds of deco.
I am sure if the software could go to less than 1second you would end up with .3 of a second.
