I feel that, while an interesting idea, this will not be tremendously 
useful. I see 2 main reasons for this. 1) Only fresh water dives show 
relevant thermoclines, and dives at sea tend to have a very limited 
temperature change over depth (over the typical range of diving depths). 
And 2), more important, I think that a lot of DCs have a very poor 
temperature sensor (as in slow responding). That is, as you correctly 
said, already visible in the 1 mock up dive (and I believe that the used 
OSTC has a very decent, as in quick responding, temperature sensor).

In cave diving, water temperatures are relatively constant, but when 
there is a difference, the most interesting, is the place where that is, 
so directly related to time, like we have now. So no added value there.
