How do you guys analyze play? If you look at the entire hand, then perform you analysis, isn't is automatically flawed? What good is it to analyze the turn if you have no idea what happened on the flop?

Analyzing a hand is done by
1) Opponent reads
2) pre-flop
3) flop
4) turn
5) river

Analyzing the river before the flop would be useless, as would be viewing the results before seeing how the hand played out.

I'm not saying that results should change how we analyze someones play. But I also don't see the harm when someone is giving us additional information to validate #1.
