After looking at the steady state data for a while, I noticed that my with skirts data was about 1% lower than the base line. It is well within the Standard deviation of the data sets though, but I think that it is lower. I think I know why as well, the wind. I noticed that during the 3 hours of testing the wind went from not much at the start, to gustier on my B test. For the A2 set of runs the wind was almost none, only a few times did I see leaves move. For the B2 set it was back to windy (it rained 20 min after I stopped testing). Since I was looking for a change at the margins of the data I think that the wind (and time) invalidated the results.
Other ideas?
what should I change if I try the test over?
