It seems when you rotate knobs there is more precision behind the scenes than is shown in the display. This means that you get what is shown in the subject, but also that you don't know if you have dialed in 1.51, or 1.54 when the display only shows 1.5
This makes it impossible to sync rates between effects etc.
I would like to suggest that we either show more numbers in the display or round off to the precision shown.
