[Article] update to Zattera's slot machine

[oshfdk]

Coverage gets quite good: ~100%. Nbits_tokens is 488975, and Nbits_tokens/Coverage is 490014, quite good values. Loop-Lay was slightly better, at Nbits = 486946 and Nbits/Coverage = 487859. The best grammar I ever found (unpublished in detail, just posted in a thread) improves a little more:

Does the number of allowed loops affect Nbits in any way? Assuming the same slot assignments achieve 95% coverage for 4 loops and 100% coverage for 5 loops, is it possible for the Nbits score to be worse for the second grammar?
