How to tell which areas of a mill should be full of oil?

Alright, let's get the obvious smart-alek response out of the way: "If there's a ball oiler or lubrication cup, you should oil it!"

Understood. My question is, assuming a "dry" mill, is there a way to tell which areas of the machine should be full of oil vs. a drop here or there?

The context is that I am rehabbing an Induma 1S machine, and a previous owner had, for reasons that I am not able to determine, decided to use grease in the gearbox(es) instead of oil. So, one of the things I have been doing is cleaning out the grease and getting the machine ready for use with proper oil.

I have reasoned (though will gladly change my mind if someone with more experience straightens me out) that any cavity that has a lubrication cup should probably be filled with oil; as I understand it, lubrication cups should show some "standing" oil when topped off, and the only way to make that happen is for the cavity into which the cups are installed to be filled with oil to the level of the cup. Makes sense, right?

My main question is in regard to ball check oilers; there are several areas of the head which feature ball check oilers, which seem to be intended for a significantly lower volume of oil than are cups. I can see how those areas of the head might not lose as much oil as other areas, so what I am wondering is, are the ball check oilers there because replenishment volume is low (compared to areas serviced by cups), or because the entire cavity within the head (that is serviced by the ball check oiler) doesn't need to be full?

Thanks for any assistance/guidance you can provide.
