Grimbles - I'm on the phone so difficult to search on you to remind myself of your history and your starting point, but......
Remember this is a marathon, not a sprint. 5lb in 11 days is good. That's c3lb a week. Yes, some of us get a bigger initial drop, mostly of water, but then we might have a bigger/longer "stall" in weeks 3/4/5.
It also depends ok how close you are to your target.
Once you settle in to this WOE, while it's nice to get a 2lb or more drop in a week, 1lb is still good. And remember, this is an average - some weeks you might STS - or even go up a pound.
The point about this WOE is that you don't need to feel like you're starving yourself.
You asked a wee while ago about if/when you can ease up on the WOE. For me personally, I've been able to have the odd piece of cake/peppermint crisp/good chocolate if I really want it. And if I do, I make myself eat it mindfully. Appreciate it, and then go and drink loads of water and get back on the wagon and avoid BIWI's big stick
