Deep Stops

[Weston]

I just read a fascinating article in the recent Dive Training about the recent research into deep stops, that is taking a safety stop for one minute at half your deepest depth before slowly ascending for a 3 minute safety stop. The theory behind this seems to make sense. Basically, if you dive to 100 ft, make a one minute stop at 50 ft before the 3 minute safety stop at 15-20 ft.

Here is my question: How does one factor in multilevel diving? Often during multilevel dives, the dive will reach, say 100 ft, and then spend most of the dive time at 60 to 70. For deep stops, would one still make the 50 foot stop for make the deep stop at half the depth most time was spent?

Any thoughts?
