For dives without mandatory stops, only GFhigh is used, even if a GFlow is defined.
Twin GFs (e.g. 80/80) have the same effect than artificially increasing dive time (time taken into account is greater than actual time). Using printed dive tables, it is like an "impromptu addition of extra increments of depth and time beyond those actually required by the dive, universally known as ''Jesus-factoring''".<ref name="Shields" />
Asymmetrical GFs (e.g. 30/70) can be used to force deep stops (e.g. heliox or trimix dives when the algorithm used is not sufficiently conservative). Deep stops can be defined as follows: “one or more voluntary or empirically derived decompression stops that are deeper than any prescribed by the algorithm utilized”.<ref name="Deep-Stops" />
GFs can be implemented in dive computers in three ways:
