i don't recall asking for your help and i absolutely did not claim my opinion as the sole truth. my point is only that the sidewall markings are hardly gospel and fail to take a lot of things into consideration. will they 'work' for everyone? sure. so does the abacus, but it's not optimal.
the research i mention is out there (if i had a link handy, i'd provide it) and convinced me to experiment and develop an opinion. my opinion is merely anecdotal evidence.
so what pressure do you ride? tire size? weight? road conditions? and most importantly, what does your sidewall say?
