^ I've had this happen too on the 11 versa but the other way, it'll sometimes jump from 6-10 which is a pain if you're climbing cos 6th is about 55" and 10th is around 115". As you said, once you get the feel for it it's ok and rarely happens any more.

What do you think it's from? My guess was from the cable stretching a bit and messing up the tension to change the gearing (just by a small amount, but enough to interfere with smooth steps)
