Sounds weird, but I'm frustrated at this ramp-up:
1-2-3-4-4-4-4 .... gone.... (all ahead)
This pattern on ANY band simply screams IO paranoia.... However, in this case, as in a case I've observed before, is likely a cop ahead on the road that turned away. As a result, I have to stay on FULL alert for at least 3 miles (plausible IO range of the V1)...
