This re-rating process has occurred already since 2012 over and over again when the new system was initiated. It should be obvious to everyone that there were still errors/bugs in the algorithms back then that needed fixing. Also, another problem was how to represent the Contractor rates separate from the market rates. This too is now all fixed. The rates change because they re-run the application from time to time, just as they will do when it all goes live someday. So right now, it is still in a “BETA Test” mode. They are still flushing out bugs but it is now very stable.
