Event within the same tire manufacturer.
For the 23 size Continental, front mounted, folding (Kevlar bead), 110psi, same load:
Gatorskin: 2096 (consistent for 4 different tires)
GP4000S: 2103 (only one tire)
These values result in matched distance measurements to better than .01mi for a 8.55mi route. 14 data points for the GP, hundreds for the Gatorskin.
