It seems that for Non-deco diving within recreational depths, that waiting 12-24 hrs seem excessive.
If you think of going from 80 ft under to 8000' above sea level with decompression stop (on the surface at sea level) that is wayyyy longer than even the longest deco stop that tech divers do when coming up from 200' lets say (I think 45-60 min of total deco if they come from 200' for 15 min BT on air)
So why for just an 8 ft equiv of water depth pressure change would you need a 12 hour deco stop before going to 8000'
(I use that term loosely as thats what it really is when you have a 12 hr deco stop on the surface before only going up the equiv of another 8 feet)
Doesn't make sense. Seems like any rec dive within NDL that you should be OK to go to 8000' in an hour or so just by comparing it to the deco obligation times of deep divers.
