Your Daytona data are good. The first timegrapher data set I see for a 4131 caliber, measured along the power reserve.
My graphs for amplitudes, rates, and the isochronism are below.
The isochronism of this 4131 caliber is much better than for your two GMT's. From full winding to 60 hours, the average rate of the 4131 remains within -2/+2 s/d (indicated by the blue shaded area). This is excellent.
