UPDATE:
While the the patch in this location (1/2" from rib of sidewall) held the air very well initially, after 4 sort-of-quick canyon runs I noticed that I am losing about 1.5 PSI in that tire. The soapy water test confirmed that the patch has a very minor leak, probably from all the shoulder and sidewall stretching loosening up the patch.
I ordered a new pair of rears and will have them installed next week, but a series of donuts and burnouts to kill off the rear tires have reassured me that the risk of the imminent failure on the patched tire is small to none--rather, it is important to monitor TPMS screen and see if you're well below the recommended tire pressure.
