Depends, I'd say.

In your scenario I wouldn't have let him pass and I would have been disappointed if I was him and you'd just let me by.

But if I'm in 8th position and one of the fast guys ends up behind me (for whatever reason) I usually let them pass, because there's really no point in putting up a fight for a position like that with a guy who's way faster than me.

Generally speaking, I always try to keep an eye on how much the guys behind me are gaining on me. If somebody gains more than two seconds a lap, I just let them pass.
