The slope (S) and intercept (I) values for the duration-amplitude (D-A) relation were obtained from a linear regression of the main sequence for duration for amplitudes >4°. The slope and intercept values for the peak velocity-amplitude (PV-A) relation were obtained from a linear regression of the logged main sequence for peak velocity for amplitudes >4°, such that PV = I.S^logA (see Methods and Fig 1B, C).
