We are brand new to this. Our PB suggested we run our VSP at 1700 8a-5p & 950 5p-8a over the winter in NC where it doesn't get too terribly cold. After reading several other forums, it seems like this may be way too much. When I asked how he got those numbers, his reply was that he's just been doing it long enough. Can you help me understand how to determine my run times/speeds? What constitues low speed versus high speed?
