It's not a protocol, in that Fezz has specifically said it doesn't bother him, provided the content is germane to the thread, at least. "Good call," not so much.
Don't think of weight as an X. A five-weight bet doesn't necessarily mean a 5-unit bet. In the case of Cincy/Houston under, expect a 2-weight playback on the over at post. His higher-weight plays are usually in anticipation of a line move.
