I am following 'Simply Rails 2' by Patrik Lenz..

I have just created the 'Vote' model and have noticed that my file names differ from that suggested in the book:

SR2 states that each new migration file should increase in single increments starting from 001, i.e.

Although these file names are in an ascending order, there doesn't seem to be any standard incremental increase between these file names.
