"Might". See Wwest. You dont' have any AC experience with a 911 or 930.
You are guessing. Guessing just like you have in all the 100's of posts you make here.

"Meager" thats just about right. The 911/930 did not have any pressure switches.
And, most TEV systems don't use a low side switch to cycle the system on and off.

I'd say your memory is selective.
And, I'd say if you are seeing a 40 psi equalized pressure you are either totally
trying to B.S. the forum here or its 30F outside when your checking those pressures

. LOL Wwest I know the answer.
So, how many 911's and 930's have you put AC service gauges on during the past 30 some years? Wanna put your money on the table?
