Rain Sensing Automatic Wipers Sensitivity (no intermittent mode)

There isn't an intermittent mode like in my previous vehicles and the Lo setting is too fast so I tried putting the lever from Off to Auto (with the dial turned down to the lowest setting) and the wipers are still too fast for my liking. After getting tired of manually bumping the lever up to mist during these occasions, I accidentally discovered that if I move the lever down to Lo and then up to Auto I get the desired affect of what seems to be an intermittent auto mode. Can someone verify this? I haven't seen anything in the manual about it but it seems to do the trick.
