I don't see the need to over simplify this into sound bites, its not like it's that complicated in the first place.
That's right. If you're going low on the GS, you pull back on the stick. If the speed the changes, you put the power up.
If the speed drops, you put the power up. If you then start going high on the GS, you push the nose down.
Simple!
In an ILS, I know that many use thrust for glidepath and pitch for speed.
Trained by C150 pilots, fly like C150 pilots. Wrong.
