It is based on how much the air shutter has to be closed to get yellow flame tips, more than half way and the gas opening needs to be larger, less than 75% and it is just about right. Operating the burners with just a hint of yellow at the flame tips is the most efficient you can get, wide open air and a noisy flame is a fuel waster.

Try your burners out. If you get the efficient flame that kladue described, then you're good to go.

and the orifice is the brass bit that thread's into the burner into the air shutter? or the actual tips of the burners?

The orifice is the inlet where the gas goes into the burner. Not the tips where the flames come out.
