Other claims from this paper (12)

Observation Smooth tuber dropping occurred at 0.43 to 0.8 seconds per cycle.
Observation The optimum range for smooth dropping was 0.6 to 0.8 seconds.
Observation At smooth dropping tempos, both hands moved and stopped simultaneously and rhythmically with consistent motion times.
Observation At tempos too fast or slow, hand rhythm was disrupted.
Intervention effect Tempos faster than 0.5 seconds reduced the number of dropped tubers.
Intervention effect Tempos faster than 0.5 seconds decreased plant number per hectare.
Observation Dropped tuber interval deviated least at the smoothest tempo.
Intervention effect Overly fast dropping caused larger plant spacing deviations at dropping, sprouting and harvest.
Observation At smooth and overly slow tempos, plant spacing variation was 20–40% of the predetermined spacing.
Intervention effect Slower tempo did not lower the spacing coefficient of variance.
Observation The upper limit of tempo maintaining plant number per hectare was estimated at 0.5 seconds.
