You are giving a presentation. This line is the line of the reasonable level of expectation that everyone has when you walk into the room.
You begin to present, and you come above the reasonable level of expectation; everybody gets enthusiastic, people begin to start asking you questions.
And about right here you reach the highest appreciation you’re going to get for this presentation.
At this point, somebody is going to make a rebuttal to your presentation. You’re gonna sink a little below that line of expectation. You grab it back, and you make some concessions. And you get up to about here. At this point, this is as high as you are ever going to get.
