Janos, I think the kicks thing is probably down to "how do you ?" type thing when out of the water.
RichW seems to have nailed this as on Fundies we did it laid on a table and it worked fine IMHO, Rich was able to stand behind and move your feet in the proper way so each person could get the "feel" of it.
Good icebreaker as well, as everyone gets to look a complete burke before you even get in the water and make a
real hash of stuff.
Valve drill makes sense to me as it stops the ability to turn off all your gas (now who would do that

)
S drill, holding the second stage IMHO is boll*x, you should be able to stow your stuff on your own. I'll try it, but at first thought it would seem to be potentially a mess with someone hanging on to the reg.
Pocket contents I will argue about when I've got the rest of it nailed, eg bouyancy, trim, team awareness etc etc. IMHO opinion as long as the team knows where the stuff is, is that not good enough ?
Personally I've got too much to work on to be worried about some of this stuff yet.
Must be nice to be so good that you can spend time worrying about boltsnaps or dbl enders on lights
Maybe one day I might get there
