I dunno -- seems like that would have much less of a percentage basis than just the effects of being in shape vs. not having paddled for a while. I suspect that it would tend to get lost in other variables, if for no more reason than my "monthly average speed" includes a lot of different variables, and can be taken only as a generality. But then, I'm not a slide rule type like some on this list, and I could well be barking up the wrong tree. I agree, viscosity has something to do with it -- hitting ice chunks while out paddling Sunday certianly slowed me down! Unfortunately, that may well be the last time out for the winter -- the lakes iced up three to four weeks earlier than last year and are getting harder. Unless we get a prolonged warm spell, I'm now an "armchair kayaker" for a few months. -- Wes *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
