Hi litlbirdie!

I'd say leave well enough alone if you are losing. What I've been recommending is to eat about 12x your goal weight which is right about where you are. The guideline in an of itself is not a hard and fast rule, but a guideline to make sure that you are getting enough calories to at least support your basic metabolic needs and not stress your body by sending it into starvation mode. A stressed body will not easily let go of weight, but it seems that you are doing just fine with where you are.
