  1. Overall there was a 10.2% misclassification rate when comparing the predicted result from the multinomial logistic analysis to the simulation results. Categories ‘forward tip’, ‘rolled over’, and ‘stopped’ all had F1 scores over 0.9, and ‘backward tip’ was the least accurate category with an F1 score of 0.595
