The deco stops will kick off once NDL goes below 0 (meaning SurfGF is > GFHi, or more precisely shouldn’t it actually be:
‘GF99 if immediately starting surfacing at an estimated ascent rate > GFHi’ as NDL does take into account off-gassing during the ascent?).
When NDL goes below 0, some deco stops are now required but these stops can clear automatically before reaching them (due to the off-gassing happening in real time while ascending at a rate different from the estimated ascent rate, for example different from 10m/min).
On top of the discrete deco stops that are multiples of 3m, there’s a CEIL depth which is the non-rounded minimun depth below which we must stay (as per the model, and based on the pre-defined GFLo for the first stop and GFHi).
-> I assume this CEIL, like SurfGF but unlike NDL, doesn’t take into account the off-gassing that will happen while ascending from current depth to that CEIL value? And that is why we can have a ceiling with NDL > 0 (and no stop)?
