  5. I made a test with RED and I use my ligthmeter to 125 Asa for tungstent light and 160 Asa to daylight. Of course you can use other sensibilites but you are loosing detail on shadows and incresae noise. As you now, 320 Asa in camera is a metadata and it is not nominal sensibility or efective sensibility, nominal or efective sensibility depends of S/N signal and saturation base either of the sensor and electroncic device.
