Fig. 7. Correlation between downstroke deviation and the mid-stroke angle of
attack, tip velocity and translatory force for the experimental population.
Black circles indicate values for the individual shown in
Fig. 6. (A) Correlation between
downstroke deviation and mid-downstroke angle of attack
(R2=0.41), tip velocity (R2=0.22) and
translatory force (R2=0.58). (B) Correlation between
downstroke deviation and mid-upstroke angle of attack
(R2=0.06), tip velocity (R2=0.05) and
translatory force (R2=0.23). Five separate regressions are
shown for five individuals.
