Clutchiness Updated, Note
First of all,
the clutchiness numbers have been updated through August 3rd.
I've been working with a feature of Excel that may open the door to daily updates (yet to be decided). I tried to use this update to teach myself how to work it, and it's definitely promising, but between that novice state and my limited time due to moving, I wasn't able to include pitcher's batting stats. So while their WPA numbers are updated, their rate stats are not, and thus their clutchiness numbers are incorrect. Hopefully that specific aspect is not your sole interest.
Remember: next update will be Monday.
