Unrealistic Cadence Behavior with Rolla Band

The experience during virtual jogging with the band as a data source is very, very unrealistic. Basically, the more realistic the movement is - the cadence is more unrealistic.

The cadence works fine only when the hands are kept in a 90 degree position and the movement is minimized almost to none. As soon as I start moving my hands in a natural motion, the cadence drops to numbers like 100spm and gets unstable.
