You know, the right number of steps isn't as important as doing the right steps in the right order. Regarding descent, the problem I see with the 5-pts decent is that it's actually not the "descent" protocol. It's the "prepare to descend" protocol.
The steps are
- Sign
- Orientation
- Regulator
- Time
- (equalize and descend)....
The first 4 steps still make sense but they are in the wrong order. On a real world dive, you first set your compass (orientation) and then regulator in the mouth and check the computer before descending.....
...... all of this is stuff that is "preparing" to descend..... none of it is actually a descent, which in my mind makes the "descend" sign as initiator illogical.
That said, I still teach them SORT(ED) (in Dutch we call it TOSTI, which is a grilled cheese sandwich) but with the step that the first sign is the descend sign to initiate going through the preparations, and that the preparations are confirmed with OK before actually descending. This way my students are still on the same page as everyone else but made aware that they are not actually descending but preparing to descend. The OK for confirmation is also the last moment to give a STOP sign if something isn't just right.
The descent itself is where the 5-pts descent stops but it's the point where I'm the most picky. I teach them to vent until their head is completely under water and then to STOP venting, clear their ears and pitch forward to go straight from a vertical descent position and get into a normal "dive" position as soon as they can. .... exhale to get deeper if needed and to descend a couple of meters at dead slow tempo. The slowest diver determines the tempo for the buddy team and if they don't stay together and descend as a unit during the descent I will debrief it as "sloppy" at best. OK during descent and upon arriving at depth.
*That's* a descent protocol. It starts at the surface and ends with the OK at target depth.
What they really need to remember is this:
1) sign to initiate
2) three last minute checks
3) ok and descend
4) go down, stay together
5) ok at target depth
STO-GO
Anyone else open for a new paradigm shift?
