Repeating wrong technique isn't going to make it right. I explained why on the previous page.
The comparison here of autopilot to human is wrong, in that an autopilot is designed to make corrections a number of times a second, which makes speed instability a non factor in flying an approach. The aircraft longitudinal time constant is significantly longer, making autopilot control effective, however a human burdened with multiple tasks, is unable to effectively cope, because of our inherent time constant, especially during multi-tasking workload.
