RF Mileage Cumulative?
Probably a dumb question, but if an RF says 50 miles prior to repair without damage occuring, if you go say 40 miles after a puncture and then get it repaired, do you only have 10 miles left the next time?
If so, I guess this means if you had to go the full 50 miles to reach a repair facility and they fix it, you no longer in essence have a run-flat - is that right?

Good question - however there is no clear cut answer.
First, the mileage is not cumulative.
However - depending on the type of second flat (I.e., sidewall, in the same area as the patch, etc.) it is possible that the sidewall might not allow any protection.
EMT's have/had a warranty "suggestion" that the tire be replaced depending on the type of repair/issue that caused the flat originally.
Best suggestion - rid yourself of the EMT's. Get non- EMT's and carry a repair kit (12v compressor/tire plug kit/pliers/flashlight, etc.) and/or a AAA card and cell phone.

I have to imagine the 50 mile limit is due to heat buildup breaking them down. They limit it to 50 so that they aren't liable to recalculate for someone who would be willing to stop and let the tire cool off back to ambient. If the tire had a total of 50 miles it could be driven with a RF then there would be very little reason to promote repairing them let alone any liability for the shop willing to actually do it. How would they know you drove it 51 miles?
