Testing the Measurement Interval

The 10-second measurement interval used for the first measurements sets in this investigation was exceptionally short. Was that decision too conservative? Is an interval of 96 seconds, as used in later measurements acceptable and more rational? This graph was plotted to test those questions. What do you think? The span of this graph is 30 minutes (to allow horizontal separation of points).

Comment: Each "box" on the graph represents a single measurement; the subsequent box is that same variable 96 seconds later.

Question: Is 96 seconds between measurement samples capturing all the water flow events, or was the shorter interval wise; does it matter whether spigot temperature or condenser fin temperature is being sampled; what might account for the difference (linear "decay" versus curvilinear decay) in response shown by these two sensors?
