Hi calum,

We do have the programmers looking into this as there is something going on with the calculations. The calculations are supposed to run weekly and when it doesn't complete then it tries to run daily. We think that is part of the problem in the changing of the calculations.
The programmers will get this resolved but please know that is NO wrong doing on your part whatsoever..

We will update you as soon as we have more information.

Thanks
Stacey
