EVF lag times: E-M5 sets new record

In the other thread, one of ljfinger's arguments was:

​A human controlling a camera based on visual feedback is a closed-loop control system, same as an amplifier. Add delay to any portion of the control loop and you decrease phase margin, thus decreasing the performance - and the maximum potential performance - of the entire system.

While this is absolutely correct, this test shows that the slowest component in the loop is the human, by a factor 10. To significantly improve the system's tracking performance, it is the human who should be eliminated, not the evf.
