A couple of additional items:
If you need to stall a shot, you don't want to feed. It's hard to sort out whether the +1 is a food inflated number. Also, when you stall, it's helpfu to re-test in 20 - 30 min. You want to catch the numbers as their rising and you don't want to throw your schedule totally off.
I would like to strongly encourage you to get at least a before bed test every night. It would have been useful for you to know just how Joplin got to that blue this morning. Having one or more tests in the PM cycle is very important -- otherwise, you're missing half of your data.
