Im not up on the JUDD plan, but as I said, with Wendy you still consume the correct amount of points over the week, you just have some low days and some high days. For example, yesterday I had 27 points and today is 42! My usual daily allowance is 30 points per day but I will still only have 210 points over the entire week. It has worked for me in the past and there are numerous threads on here about it. Alternatively you could google it.
Hope this helps - Gerry
