While it is only a small factor, I'll note anyway that the "time to
discharge of a capacitor" is generally considered (read stated in most
books) to be about 5 time constants. This would make R*C~0.1s (=0.5s*1/5)
and therefor (if C~1F) R~0.1ohms.
BTW: When I was a young student (~1960), the time to discharge was
considered to be about 7 time constants. I'm not sure why the change!?

If 1/2 second is needed to discharge a supercap then R*C is about 1/6 s.
If C=1F then R=1/6 ohms. Yes, this is significant but not really very large.
