Fold Lays

Think of it as units per hour but at a section level. This
allows it to calculate correctly with standard jobs and folded book sections.

Take a 16pp book printed as 2 x 8pp sections for a qty of
500, but there is an actually 1,000 fold lays to go through the folder.

If it was just using a standard 'Units Per hour' it would
look at the job qty of 500 and calculate the folding time incorrectly.

Sheets per hour is based on printed sheet qty, which may not
be correct as the printed sheet maybe cut down before folding? E.g. there may
be 2 x 8pp section printed on the sheet. These then need to be cut down before
they go through the folder.
