I Heavily disagree with this point For 2 reasons
1. its not just what they say its How they say it.
Chuggs and Hedin for example became instant town reads for me based on reaction to miller claim and they reacted in very different ways.
I never read people on some robotic "Did they beleve miller claim or not" I read them on How they choose to engage in the thread, word choice, decisions etc.
2. People reacting to the miller reactions was super useful in killing Ephi and Zipped
Every Gambit I do is not just accounting for reactions but people Reacting to reactions. This go Layers deeper than some simple "do they believe im miller." that was never the point
I think you are over estimating your gambit.
