I'm with Vinland on that, I feel like they repeat throughout that there are situations where certain pot sizing methods would be fruitless without explicitly naming which situations would be bad. It also allows you to tailor the ideas to the individual villain. Again the pot sizing example comes to mind as the book gives different scenarios based on different reads.

The overall message I got from the implied odds section is, "Either force your opponent to fold or trick him into a -EV call based on stack sizes and reads" That makes sense to me for the most part but I dont see how you would figure out the right bet size without calculations on hand.. other than looking at the hand after the fact and learning from mistakes.
