Is it really ?

Here is an anecdotal comment...

I have been diving with GF since almost day 1 when it was introduced (i.e. 9 years ?) and have always use 10/100, except for the first year at 20/100.

The diving in the last 5 years have been 90% decompression, minimum 70m (shallowest wreck available) to maximum 120m with long'ish bottom time (i.e. not 1 sec at max depth, but typical of 35-45 mins at 72m).

Never a niggle, never feel sleepy or tired afterward (because I have to drive 3 hours to go home after the dive).
