comment Can I use a 9-speed shifter with with a 8-speed cassette?
Ok, I re-read the article and now I see that the max error between Shimano 8sp and Shimano 9sp will be almost 1.5 mm ((4.80 - 4.35) * 3), so this setup is not going to work well even in theory. Thanks.

Sorry, I linked to the wrong chapter within the article. I was referring to the "Sprocket Pitch" chapter: "...some "incompatible" combinations actually work okay – at least when new. ... If, for example, the mech shifts 4.55mm instead of 4.35mm, the most it'll be out is only 0.6mm, and only in next-to-top or next-to-bottom. The rest of the reason is that the guide pulley can float about half a mm side to side, allowing at least that much misalignment between mech and sprocket without any nasty noises." - but they also say it would only work when the parts are new and ideally adjusted.

Thanks for your answer. For completeness sake - an article here: ctc.org.uk/DesktopDefault.aspx?TabID=3946#Shiftratio - suggests that maximum error in an ideally adjusted 9/8sp combo would be about 0.6 mm which is less than the derailleur's "wobble" or margin of error, so in theory such a combination could work after all. But it definitely would require more accurate adjusting.
