this is cool - i've spent way too much time just sort of synthesizing this sort of data in my brain with no hard evidence. One knob I'd love to have is the ability to tune the # of days ranges - "above 200" is a pretty large bucket depending on how you tune the other numbers. It looks this is changeable in the code, but maybe it's tied tightly to the available data?
