After Head Space Set 1 click or 2?

Was curious how many clicks out folks go after initial head space set on the 1919. I've seen the head space video on this site and he is a fan of 1 click out after initial head space is set. He also mentions some people prefer 2 clicks. Pretty sure I have a grasp on the 'why' we turn the barrel out 1 or 2 clicks (heat expansion etc.) but was curious what the preference is here by other 1919 shooters.

Lets say for example I am shooting quality, modern and reliable 7.62 or 30-06 and I'm not leaning on the gun until the barrel glows should one click out be sufficient?

Seems like I see most people speak of going with 2. Is it a Ford vs Chevy thing? Am I over thinking it and should just use 2 clicks out and forget about it?

Sorry for rambling. Being new to the 1919 enjoying learning about how mechanical things work (especially machine guns) I wonder these things sometimes.
