I noticed that last winter... on a steep enough climb, i'll totally lose cadence (mine seems to drop in the high 40s). Wahoo seemed surprised by that when I emailed them so I gave it up as a lost cause. Frankly, it's good enough for 98% of what I'm doing and I don't really care about knowing my cadence when I'm grinding up a nasty hill anyway, I guess.
