By asking the slide to overcome the spring weight AND flat FPS from a dead stop you are unnecessarily causing a delay that does not need to be there.
That smith must be talking about light target loads, or else he completely missed the point. The entire reason for changing to a FBFPS is to cause that delay, that does need to be there for hotter loads. That's the whole point.
From his writing it also sounds like he's never actually compared ejection distance with different springs to see how little effect it really has. The ejection distance is directly related to slide speed.
The fact is there are plenty of smiths out there, and manufacturers too, who have their own opinions on how to do something without really having the facts to back it up, so they make up a theory. What you've posted is a great example of that.
