The discrepancy is fully explained by variance. Some of the results that went into computing 1.424 had less than 20 samples, which is not enough to get a precise answer for such a highly variant task.
That doesn't necessarily mean that my simulation is perfect (and, another commentor has made an improvement on it!), but it does mean that this evidence alone is not enough to suspect the simulation.
