Chickenhawk, . .. .I suspect that the cancellation rate of 1 in 4 or 5 depends a lot on the runway. If you are operating from a hard surface, you will be able to fly even if the weather is poor. If you are flying off of grass and if you've just experienced most of the Atlantic Ocean doing touch & goes on your runway, then you are in for a serious tea-drinking session! . .. .1 in 4 does sound high to me, but we have had two very wet winters in succession so those figures may be the current trend.
