Getting somewhere, maybe

I know I have been blogging only sporadically, and I won't even try to fill in all the holes (sorry) but I did meet in person with ET yesterday (!!!) and it was helpful. I'm pretty sure I'm now doing the math right (basically you substitute in other things so as to avoid the lovelies I was talking about below).

Now I am trying to sign the manager's response to an increased proportion of penalties, and I am totally stuck. There ought to be a way to boil it all down to things that I can compare, but I keep not quite getting there...
