More than a few times have I seen absurd wpm numbers mentioned in a blasé manner here. 500wpm is quite achievable for a light thriller, skimming the odd paragraph. Approaching 100% comprehension provides dimishing returns with this kind of stuff. I am very happy to average 50wpm with technical or entirely novel material, since here the opposite is usually true.

Maxing at 200wpm is absolutely fine. All that (imo) matters, is it's a total waste - and a mentally taxing one at that - to spend those words/minutes reading crap & looking at adverts!

Edit: no rudeness intended to the fast readers ITT!
