Yeah, I think there's a pretty good practical argument behind what he's saying here.

You can aim for perfection as much as you like, obsessing over macros for this, apps for that, clean eating, whatever. But any progress you can make is still beneficial, even if it's not considered 100% ideal for the purists.

You don't have to get it completely right all of the time, you just have to get it right enough most of the time to still make a tangible difference, by whatever measure(s) you're tracking over that time.
