Daylight is too loose for me, no matter where or when I am in my ride. I cinch tight enough that I have to work a little to slide my hand under at the start of my ride, usually by the end when my horse has fully deflated and everything is as warm and stretched as it could be I can fit my hand under easily, but still no daylight. Be prepared for the unexpected- a bolt, startle, or spin is not the time I want to be wishing I had tightened my girth more.
A normal human using only their own strength will not be able to tighten a girth so tight it is damaging to the horse. Uncomfortable, yes, especially if it's a big strong guy, but sores, etc are from the tack not fitting, not generally over tightening.
