I love this gear searcher. I've been making a spreadsheet with it, and it's awesome!
There does appear to be an error with the max on the "stopwatch" type gear (well, I have so far only checked the legendaries).
The max cooldown time should be 10.50% on all of them, if I'm correct.
I have a maxed Aria's Encore that has that, and my Firmware update 1.51c is at 9.63 cooldown time (above your max), but only 5.14% sprint speed (below your max).
Thanks again for the work you put into it!
