Differences, associations and heteroscedasticity of the errors between the actual and predicted one-repetition maximums (1RM) during the bench press exercise.

MVT	Method	Predicted 1RM (kg)	Raw Diff (kg)	ES	r(Pearson)	r(Heteroscedasticity)
Group	Multiple-point	39.4 ± 8.6	0.8 ± 3.0	0.10	0.94	0.37
	Two-point	41.3 ± 9.0	2.7 ± 4.9	0.32	0.84	0.33
Individualised	Multiple-point	39.5 ± 8.8	0.9 ± 2.5	0.11	0.97	0.54
	Two-point	41.3 ± 9.1	2.8 ± 4.3	0.33	0.89	0.39

Data are mean ± standard deviation. Raw diff, Raw differences; ES, Cohen’s d effect size ([Predicted 1RM − Actual 1RM]/SD both); r_Peason, Pearson’s correlation coefficient; r_{heteroscedasticity}, heteroscedasticity of the errors.
