> I think this fact alone invalidates the data It invalidates the data ? How so? Or do you mean conclusion? Even so, there's nothing inherent with "a few days" that makes the analysis invalid due to sample size; that depends on the nature of the data. In my employment we are measuring changes hour to hour.
thus they need numbers over months before they can state it worked.
