If wide low pressure tires are "Faster", Why do I always feel like I need extra what's for the same speed? I always feel like I am in the mud
Who is saying that wide low-pressure tires are "faster" and in what context? Not even Jan Heine claims that going wider than a 25 will speed you up on good roads; rather, his argument is that excessive width is no big deal, so you might as well err wide for comfort and versatility.
How wide are we talking about, how low-pressure are we talking about, what
particular tires are we talking about? That last one is very important: the 52mm tires that are on my gravel bike right now are nearly 2mph faster on pavement than the 45mm tires that I've got laying around that I could swap in their place. Not because 52mm is a better width than 45mm for paved riding, but because the 52s are fast supple slicks whereas the 45s are a very beefy urban/mixed-surface tire.
Other factors like fit also matter, a lot. If you ride in less aggressive postures on your gravel bike than your road bike, your body will be creating a lot more aerodynamic drag at high speeds.
