Like mathauck0814 pointed out, the problems with RMS is commonly known, it is no secret just go on CCR Xplorers or Rebreatherworld.

tstormdiver - Not to contradict your instructor as to what you were taught, but a proper pre-breathe is done while in your rig. I have seen several problems that have come about and would have been picked up if the diver did their pre-breathe while in their rig opposed to standing next to it! Not doing this way is a bad habit/procedure to use. I understand about drysuit, water temp, over heating, I am a NE diver. Do a quality pre-breathe (while in rig) and knock time down to 5 min.

I am typically technically in the rig (not standing beside it), as I have the loop & lungs over my shoulders & monitoring things through the HUD & handset. I am not usually fully dressed nor in the harness & the delay between getting fully prepped & jumping in is not normally more than 15 min. If 15 min. makes that much of a difference, then there are much more serious problems to be delt with.
 
Having the unit sit for a period of time after prebreathe is only a fraction of the issue. Things can change (gear jarred, something cut, torn, caught/hung up etc…) while we are physically in the act of getting in our gear, so this is why. Think back to basic open water class, we assymble our gear and check everything (test breathe regs, check gauges, inflate/deflate the BC etc..)out ourselves. Once in our gear, the buddy checks are done, how many times have problems been picked up there? Hey, I just read your post and commented on a concern I had and something i do and teach differently, this is what makes my students and comfortable stepping into the water. In the end, you are the one diving the rig so choice is yours.

If that sort of thing happens (such as when my unit fell off the table a few months ago).... I go through the entire operational checklist again (including checking the sorbant & O2 calibration in O2 & air). There were isssues from that fall (torn hose & cracked manual O2 addition valve). Going back through the checklist caught it. I replaced the parts that were damaged & went through the checklist again & again, until everything was operational as it should be, before getting into the water. If *anything* is amiss, I can assure you, I do not get in the water until it is resolved, repaired or replaced & proven through the checklist to be fully functional. I don't just jump into the water with it, never. I am fully aware of what that unit can do if not respected. I am not disputing what you are saying,.. but let us admit,... one size does not always fit all. Some circumstances do not always allow for that. If it were a perfect world,... yes then perhaps one size could fit all.
