What is the drive ratio, metering oil pump : eccentric shaft?

Hello people!

can anybody tell me what the ratio is between metering oil pumpís rpm and eccentric shaft rpm?

for example, 1:2 ó one turn of the MOP for two turns of the e-shaft?

I never checked, but since it is driven off of the same semi-worm gear that drives the distributor, geometrically it probably turns at half eccentric shaft speed.

I vaguely remember the gear being the same diameter as the distributor, as well. I never checked, as I generally chuck all that stuff and plug off the oil hole in the front end housing.
