Do you really have nothing better to do? I know that the 92W-880S onramp is metered for both the HOV lane and the regular lane. I assume, but do not know for sure, that the case is the same for the other direction. From what I remember, the 92W-880N onramp is also metered the same way, so I assume that all four onramps are metered the same way.
The post regarding the MissionE-880N onramp was in response to your post where you questioned whether the HOV lane was actually metered or not. I would have shown the exact onramp the OP is describing, but Street View is out of date. I offered the Street View to show that the HOV lanes do have the potential to be metered.
Regarding the pattern, apparently I need to be more specific. When the lanes are metered, both lights are red, and then flash green to allow a single car to proceed. The scenario I described is where there is a line of cars waiting in the non-HOV lane, going one at a time. When a non-HOV car goes, the light then turns red, and the next non-HOV car coasts up to the line. In that case, when a HOV car comes along and stops at their red, rather than the non-HOV car being allowed to proceed, the HOV car is allowed to proceed first instead. The key is that the HOV car is still required to stop, just, in my experience, their wait is less than the non-HOV lane. This is what I have noticed for all metered HOV onramps in the Hayward-Fremont corridor, though not specifically the one that the OP is referring to.
When I said that I haven't discerned an obvious pattern, what I meant is that I haven't seen anything like 3 HOV cars for every 2 non-HOV cars.
