Comparisons of every 10th replicate showing differences in the prior distribution, number of calibrated nodes, and relaxed clock simulations.

Average (Avg.) minimum (Min), maximum (Max), median, and credible interval (CI) values are the averaged absolute summed differences between primary and secondary estimates in time units (Ma). The uniform and normal prior distribution replicates and relaxed clock simulations applied a single calibration, whereas the two node replicates applied two calibrations per replicate, both of which have a uniform prior distribution. The T-test results are the proportion of replicates that resulted in a significant value at P
