I can imagine this problem. I've had to deal with similar things  
myself. The problem is basically that LCD updates take (relatively) a  
long time, whereas rotary encoders can be quite fast. So if someone  
turns the rotary encoder really quickly, you can't update the LCD  
before the encoder has moved again. This leaves you having to choose  
between letting the LCD update finish before you check the rotary  
encoder again (e.g. ignore the encoder) or check the encoder but  
don't always bother to update the LCD if it's going too fast (e.g.  
ignore the LCD).

It's pretty much got to be one or the other, and that isn't anything  
that Dave Smith or anyone else can change.
