Hi all,

I've just got a question about dive tables that has stumped me for a while.
Now going by PADI's dive table after 20 mins at 100 feet you have reach
your no-deco limit and end up in pressure group O, where as at 35 feet
you have to stay down 205 mins to reach your no-deco limit and there you end
up in pressure group Z. Now correct me if I'm wrong when I say the higher
your pressure group the more nitrogen you have adsorbed, which leads me to
my question which is why is the no-deco limit for all depths not at the same
pressure group?

Thanks,
Daniel Taborsky
