Samson fid chart typo?

[Newse Neus]

Why is the 9/16th short fid shorter than a 1/2 short fid? Is this a typo?

No, my Samson aluminum 1/2" & 9/16" short FID length measurements match the table.

Crazy, I didn't think it was an error. I'm just curious why the larger diameter is shorter not longer.

They sort of explain the math here. Top right of page 2.

Short fid for 1/4"-1/2" is 37.5% of a fid.

Short fid for 9/16"-3/4" is 30% of a fid.

Interesting,never noticed that before. So larger diameter ropes squeeze better than smaller. And for some reason the cutoff point between the two is 1/2 and 9/16.
