Drafting rules is really hard; it is an art to be able to draft rules and/ or statutes. Knowing the substance is half the battle but getting unambiguous rules on paper that cover most situations that arise is not easy.Sorry if Bob or anyone else here wrote the WPA rules, but why are they written so poorly/ambiguously. In this "calling obvious shots" case, the CSI rules are so clear for what must be called, while the WPA leaves one scratching their head. Same thing for the push and double hit shots from last week. The WPA rules stink the way they are written.
I vaguely recall Mark Griffen wanted the CSI rules to be written from scratch to be clear, because the other rule sets were always ambiguous.
