Currently, the OC Tec mode allows the user to specify an alternative data display to replace the NDL display in the bottom right. This is because once the NDL has been reached, the NDL display is useless and wasting space.
I would like to point out that the deco stop displays (depth and time at next stop) are also wasted space as they are left blank before the NDL is reached.
I understand that the OC Tec mode is primarily for divers breathing helium (meaning deep dives where narcosis is a problem) and therefore NDL times are often very short and the time that the deco stop data frames are blank are also very short. But I happen to like the OC Tec layout and customization as a recreational diver.
It would make sense to me to place the NDL data frame in the upper right, and simply replace it with the deco stop depth/time frames when the NDL has been reached, since the two data frames are "mutually exclusive" and one is only relevant when the other is not. That would free up space in the bottom right of the screen, and the PPO2 data frame could be moved to this location. This leaves all three data frames in the center row open for customization. In fact, this entire customizable row could then be moved down to the bottom, leaving all the important information in the top two rows and three slots for customizable data frames in the bottom row.
Also, if anyone from Shearwater might read this, I have noticed two things. First, average depth is not available on any of the cycled data "pages" when using OC Rec mode. The only way to see average depth is to choose the max and avg depth data frame as one of the two bottom customizable displays. Second, when the screen is inverted (I like to wear the Perdix on the inside of my wrist with the battery compartment inline with the center of my forearm), viewing a dive log does NOT display the graph of time versus depth or temperature. The line representing this graph does not appear until the screen is reverted. This appears to be a bug.
