I did not, and yes it is in relation.
For example, if we knew enough about the water (ie. chemical comp., temperature variance, wave peak/min frequency and p/m amplitude ect...) and if we could at will manipulate those "variables, " then, if done in the correct way, we could move the people around in the pool itself. We could change parts of the water to be cold were the people are, but inject streams, bubbles or pockets of warm water to attract them to different locations. More simply, somewhat like you stated, we could drain the pool they would all probably on average get out of the pool cavity faster than with the water (so we still would have accomplished the objective of getting them out faster).
This may be too big of a leap (logical, not explanatory), but assuming this leads to everything being manipulatively determinable, at least socially (not on an absolute physical level). Therefore, it seems that there should be equivalence, since we assume the (predictable, calculable...)adaptation to outside influence.
