She thought to herself "hmmmm, my bean is starting to get the hang of this, what to do, what to do? oh I know.... a PINK #, that'll throw her off!!!!". Sometimes I am convinced the kitties are plotting against us!!!! ohmygod_smile
It's a puzzle. Could be the dose was too low. Could be the dose was too high (though she likes her greens, so that wouldn't be my first guess). Could be some wonky factor that threw this cycle off (got into dry food? some weird stress factor?).
More or less I'd say you need more data to know for sure what is going on. If you get an inverse curve pattern - stays high all cycle and drops at the end, dose was probably too high. If you get a shallow U-curve - maybe she drops a little from here, but not too much, and then goes higher as the cycle ends, dose was probably too low.
