I found the version of the PADI dive tables on the 'net, and it appears quite different to the one that I have.
The obvious differences are that it includes some deco obligation dives, and there are only 14 pressure groups. It also seems a lot more agggresive than the ones that I a familiar with.
As a quick comparison, a 30min dive @80ft followed by a 60ft dive after a 1hr SI, gives me an NDL of 29min on my PADI tables, but 56min on these tables. Quite some difference!!
Can anyone shed some light?
