Ok I see, looks like you are worried b/c the PMPS is so much lower than the AMPS, and it looks like a 72% drop which is slightly high (though might be ok). Maybe try 1.1 then? I wouldn't say 1.2 was too much though, I would say it's perfect for a higher PS. And I don't think it would be a problem if you want to shoot 1.2 tonight since the PS is already going to be over 200, but if you do that I would get in a spot test or two between shot time and nadir. But even a 72% drop puts you at a nadir around 55 which is perfect - not much room for error, but still a perfect nadir.
