@matigo Then the variables for the A4 page time are text block shape, font, font size, and leading. Text is just a pain overall. (Luckily “close enough” is good enough for time estimates.)
(Oh and then there’s the math papers where you spend a week trying to crack a single page… So writing style, technical or crazy-long 19C sentences or 21C newspaper, definitely is a factor.)
