The analysis of the formula for strike indicates that it is biased with respect to random noise: a the individual strikes for each realization are plotted for two levels of error. The green lines correspond to 1% error and 1000 realizations. The yellow lines correspond to 5% error and 1000 realizations. The data were distorted assuming twist = 20° and shear = 30°. The dashed line represents the true strike as computed with 0.01% error. b The black line represents the estimates of strikes using 5% error and 30 realizations. The red line represents the estimates using 5% error and 1000 realizations, and the green dashed line corresponds to 0.01% and 30 realizations
