I have written a number of articles about how U.S. intelligence agencies monitored the Soviet launches, including the Proton launches, and tried to determine what their missions were:

What the evidence shows is--as you would expect--the first launches tended to be the most confusing. However, patterns quickly became apparent for subsequent launches. These patterns included the launch vehicle, the trajectory, any signals broadcast before and during a mission, and also the movement of recovery forces (if it was a robotic lunar rover, for example, there was no need for recovery forces at sea, although tracking ships would still be deployed).

I suspect that Geoff Perry and the Kettering Group knew as much, if not more, than the U.S. intelligence agencies.
Light travels faster than sound, which is why some people appear bright until they speak.

You'd be wrong. Kettering Group did not have listening posts in Turkey, Japan, Pakistan, elsewhere. They also did not operate satellites. As good as they were, their assets were extremely limited.

Not to forget: it was the beginning of a series of failures.

Yeah, Proton had a particularly high failure rate early on. It took them awhile to iron out the kinks.
