De-emphasize CNS/OTUs

[pabdakine]

Since it is practically impossible for a recreational diver to bump up against CNS limits while staying within the gas MOD, those metrics are potentially useful only to the technical diving users. However, with the recent revamp of the CNS guidelines by leading deco researchers Mitchell, et. al., those have fallen in priority as well.

TTS is the primary metric used by technical divers, so I suggest putting those in the larger bubbles and moving the CNS metrics to the smaller format and consolidate to one bubble to save real estate (e.g., "CNS/OTU 47% / 122").

I think this is a valid suggestion, I agree that TTS is an important metric that currently does not get enough attention. Whether or not to de-emphasize CNS/OTU I'm not 100% sure about just yet, I am familiar with the latest research, but it does not suggest that CNS/OTU is not important at all (as far as I can tell), and many agencies still teach these. So let me consider the possibilities here.

Just to clarify, I meant de-emphasize from the current position of (apparently) top priority, but not eliminate.
