I've also just realized that the numbers are within the range of
experimental error. I get the following angular momenta out of
Williams:
Earth Moon Total
2450 My ago 7450 27500 34950
900 My ago 6730 28100 34830
620 My ago 6400 28400 34800
Now 5840 28900 34740
That's a total loss of under 1%. Some of the source numbers are +/-3%, and
no doubt there are rounding errors in my calculations.
