I had expected that the bad coil would not flash at all. I can't imagine why a "bad" coil would flash at a different rate; either it should flash or not.

FWIW, I used the inductive timing/strobe light (hooked to coil output plug wires #1, #3, #5 (seperately) ) to find the bad coil, which flashed both slower than the good coils (half the rate?) and intermittently.
For kicks, I hooked-up the inductive timing light to the coil input wire, and it flashed at the same rate as the GOOD coils' output. I'm thinking this would be a good test to see if the coils are receiving a good input signal and if it is a wiring harness issue.
