In short: What is the rate at witch OTU's decrease?
The REPEX chart provides limits on a daily basis, decreasing as as the =
expedition lengthens, ranging from 850 on day 1 to 300 on day 10 =
onwards.
Now I know it is not in every person to blow the OTU clock on a daily =
basis, especially not on short expeditions (2 to 4 days), but the daily =
limit of 300 could be easily reached on the longer expeditions.
The REPEX chart, again is a guide line, just like deco schedules, your =
are never fully gaurenteed that it works 100%, but is there a way of =
building a credit, say should you not dive on day 4 through 6, and again =
on day 7.
I know there may not be specific answers to the above, but how do you =
treat this point on long expeditions, or is it simply ignored?

I raise this question from a deco schedule I prepared using the one of =
the computer deco software programs.  Day one conisted of two dives, 50m =
and 40m with a 5 hour surface interval.  After futher 24 hour surface =
interval the 3rd dive of the expedition was planned.  There was no =
decrease in the OTU for this period, yet CNS had decreased to virtually =
zero.  Do the two not go hand in hand.

I would appreciate any meaninful response.

Dennis Harding.
