A little nit

[Jim Jagielski]

I'll be adding some code to allow for lbfactors to be
single decimal numbers (like 1.1, 2.5, etc...)... People
have asked "How do I change it so that machine B is like 10%
preferred" and I mention that "Well, you could make one a
10 and the other an 11" but that confuses people. :/
