Rule 4
Hi, I wrote rule 4 as...
H(before 3) --> I (1). The parentheses represent a subscript by the way. I saw in the real time video Matt wrote it differently. Can someone confirm if my conditional is correct?

We could diagram the original statement as If I/= Week 1 -> H/= Earlier than 3
And the contrapositive as If H= Earlier than 3 -> I=1
Your notation was right, I think you might have gone to the contrapositive before the actual rule itself. Theres absolutely nothing wrong with that (in fact, for "unless" conditions I tend to do the same thing) but make sure to always take the contrapositives!
