Making your dives that are close to the NDL on your computer safer:
You can do the equivalent of a Shearwater adaptive safety stop using any computer. Simply extend your safety stop to 4, 5, or whatever minutes if you come within 5 or whatever you choose minutes of the NDL. I did this kind of safety stop for many years
The guesswork has been taken out. With the SurfGF function on Shearwater, Garmin, maybe other computers, you can simply sit at your safety stop until your SurfGF has decreased to a level consistent with what you want. I have not surfaced with a GF greater than the low 80s since purchasing my Teric in 2019. I certainly do not push my NDL on most dives and my average surfacing GF is around 50.
Yup I set my safety stop to 5 mins on my Perdix and like Scubadada surface with a low GF.
This is the highest GF 71% I had on exiting any of my dives on my last vacation. Most were around 40%
