Agreed - standard principle: random processes clump. You want something pseudo-random with good spacing, something like a Golden Ratio Spiral. It's suggested that plants use the golden ratio so that leaves shade each other less, because each revolution the leaves still don't line up. This is because the golden ratio is the irrational that is hardest to approximate with rationals, and that's because it's the solution/value of the Continued Fraction 1/(1+1/(1+1/(1+...))).
