Accuracy: A Note from Nick Kollerstrom

Venus's Eight Halos

Here the equation is E/Ve = 1 + sin (п/8). Taking the mean radii of Earth and Venus as 1 and 0.72333, the agreement is within a staggering 99.99% - an entire order of magnitude greater than JM has claimed!

The Crusade

Here the equation is Ma/Ju = (1 - 1/√2). Taking the mean radii of Mars and Jupiter as 1.5237 and 5.2028, the agreement again comes to within 99.99%.

So, these two constructions given in John Martineau's A BOOK OF COINCIDENCE, fourfold and eightfold, are both exact to within one part in ten thousand - a whole order of magnitude above the 99.9% there cited!
