I read pretty quickly but have never expressly timed it (400WPM on Spritz seems a bit slow anecdotally, but I don't comprehend Spritz even on low speeds).

I think what I do is read pairs/tuples of words at once, and then move on to the next set.

Eg, to quote graeme - I read [This is of interest to me,] <move eyes> [as I have much practical experience] <move eyes> [with teaching people to read faster].
