I use the digital readout from my scangauge and use my foot to set up the coast. I have a couple of markers, one for me to get my speed on and the other for the kick of the stick.
Wind is not too much of a problem down in the trees here. If it is out of the south or north it can get down to the road level, otherwise it is pretty still.
I got 61 several times on the one hill and only 1 MPH variation on the other so I am happy with the method.
My big concern is catching a dry day. Today if I get everything put on I won't be able to test due to expected rains.
I have a coast down run that was consistent, although not level. I enter that one at 50 and use 40 and 30 for the data points. It happens to be on the way to work so I will get that one done this week.
