I went from the beige menu straight to the green menu and then complained about being hungry...LOL I don't think I could have made it thru the blue/yellow ones!!!
I think it sounds like very good and steady weightloss...but everyone is different. I have had slower weightloss because I have chosen not to be perfect all of the time. I average 1-2lbs per week...with occasional 3 lb per week losses. I am good with that, but there are others who aren't.
Try to be patient with your body and with yourself. If you have been doing everything perfectly, then it is out of your control how your body responds...everyone is different. That is why there are "plateaus" etc...
Hang in there! It does work, just maybe not as quickly as you want it to
