Did you read through the calorie counter's forum? Lots of folk over there have done it.
Some folks on WW also do the "Wendie" plan which is similar.
Don't forget to search for "calorie cycling" as well. It is another common term for the same process.
I can tell you that I didn't cycle intentionally, but calorie cycling is a natural part of my plan. I had/have a range of calories - and I stay within my range. As I have special events come up, I plan for them by lowering my calories for a few days, so that I can be a bit more relaxed with my plan during those special times.
I also used calorie cycling intentionally when I hit a plateau. So, I do believe that there is some merit to shifting or cycling.
So, if you don't get any responses here - make sure you post the same question in the calorie counter's forum. They are a GREAT group what has lots of ideas that will help
And, I almost forgot:
