Assuming we are diving in the Nitrox mode, I have a few questions for the Sherwood rep (or whoever else can answer authoritatively):
1. Do the OTU's shown on the Widsom II O2 bar graph display directly correlate with the cumulative percent saturation? For example: no ticks displayed = less than 20%, 1 tick = 21-40%, 2 ticks = 41-60%, 3 ticks = 61-80%, etc?
2. From reading the manual, my guess is that the answer to the first question is No. Instead, it seems that OTU's are a combination of acute toxicity units (that is, PO2 due to depth) and subacute toxicity units (or daily oxygen exposure).
I presume that the reasoning for this combination is that during a dive, you want to be notified regardless of which one might be causing the alarm, and the remedy (to go UP) is the same for both.
On the other hand, after a series of dives, it would be helpful to know the cumulative O2 saturation for planning purposes. In the built-in Wisdom log we can view the max PO2 for each dive. Where can we find the cumulative O2 sat for each dive in a series?
3. My backup computer is a Genesis React Pro which, I think, is the same as the Sherwood Insight. In its log, it does display cumulative O2 sat for each dive. If that info is not available in the Wisdom log, would that be something you might add to the next software upgrade?
