I'm trying to research "weather stations" to see if the return is worth the investment. Most I've seen are quite pricey. What are your thoughts on them and/or experiences? Is there a basic list of variables besides temp, humidity and barometric pressure that I should be logging? Any calculations I can use to help nail my "dial ins" by plugging in the "critical" variables? I know the more data collected the better, but what/how to deal with it is where I'm stumped. Dial in and reaction time , along with consistent traction are keys to "winning" races. Traction and reaction time are things I can physically work on to improve, inconsistency due to fluctuating weather isn't. There has to be some kind of "math" to get it right.
