Glicko-2 converges within 1000 iterations or something is wrong

As described in http://glicko.net/glicko/glicko2.pdf with 15 games per period:
The main iteration of the Illinois algorithm to narrow the bracket around ln(σ02)
is reasonably quick. From simulation analyses, the median number of iterations
to narrow the bracket to a width of less than ε = 0.000001 was 5, with a mean of
5.6, and a maximum of 19 (in 10000 simulations).
