I find that the documenation for TransposeInterpolateRange doesn't tell me enough.  The 'Transpose' part I understand.  The word 'Interpolate' I understand when I can specify specific points in time such as in "Give me the temperature every hour on the hour".  Then it would find the nearest measured points and find a curve between them and find the intersection of the curve and the top of the houre.  But when that is applied to a "Range", I don't understand how PI is able to choose the point to report back as the result.


I ask this question because I saw a query written that returns an ontime of 100% for a full day, but I also saw that the day had not completed at the time that value was pulled.
