Dear List,

Please enlighten me:

What is the difference between following a deco schedule produced from a set
of (computer-generated) tables, and following a deco schedule produced by a
computer on your wrist? (Apart from algorithm differences and that the
computer produces a schedule for the dive you actually did)

Thanks,

JT
