Idle with AC and fan at max is how I do it. I have yet to see anyone do different.

Yeah I'll be driving the car later today and will take a few pics. Is yours converted to 134?
Ok cool, thank you! Mine is not converted to 134, still running R12. I need to investigate what it will take to convert so when my secret stash of R12 runs out I can make the change.

You are right. Those values are at 2K rpm.
