I finally found the right page in the FSM, 07_1-110.pdf. They talk about one drop a second.

They also talk about starting more advanced and start pulling the crank through until you just notice the dripping. Same idea as discussed but a bit more dynamic. Also they discuss the importance of making sure the engine is at full throttle and that the vacuum hose is disconnected. I have never done it and I am just quoting from what I read.
