Put some bluing on the face of the seat and close the stem. See if the bluing transfers to the entire washer face. Then you'll know.
I don't see any other possibility.

I considered that. I have coned washers on there and the washers are pushed down hard uniformly when I look at them upon disassembly and I can feel the washers compressing as I torque down the taps. The main flow is stopped with very little effort on the taps. I can torque them down further once the main flow stops but it has no effect on the small stream of water.
