In the heat of a hand I have never really thought in the kind of precision that is used in this post to answer a question about playing on the bubble. Indeed I have seen other players doing so in various situations. It seems to me that the longer they think, the more they calculate, the more precise they get about the situation, the more I am able to extrapolate about the nature of their hand. I doubt that poster of the answer in the bubble post would of been able to come up with such a precise and validated answer in any amount of time that would be practical at a poker table.
(generally exclude online play here if you would be so kind, there are tools online and this is not a question about tools and such, and online someone just taking their time may not be enough of a tell to be of any value. This is a question about the practicality of a precise thought process in a brick and mortar venue.)
Can the process of adding precision to your calculation be counter productive in the heat of a hand?
If so, when does the process start degrading your expectation?
