So here's some width measurements. I'm using Easton rims that are 24mm wide on the outside and 19.5mm on the inside. I pumped all tires up to 100psi.

The 25c GP4000sll is 1.170in (29.7mm)
The 28c GP4000sll is 1.330in (33.7mm)
The 28c GP5000 is 1.150in (29.2mm)
The author states that the 4KIIs are much older than the 5K tire, so the 5K tire might grow to 30mm.
