With my good old
20 years old keyboard I can reach > 100 with ease.
Awesome hardware btw. no computer hardware of this quality is manufactured today - built in 1992, hand-signed by 2 different QA guys, these are built to last forever (or at least, for a very long time).
Years ago, I got 2 of them in a 2nd hand hardware store for a very low price - that dude probably didn't know what he was selling there and how expensive these keyboards originally were - and no, I didn't tell him
On my notebook, I struggle to get a score of 60, so yes, keyboard quality matters a lot.
