Draw Length and Arrow Length - Compounds

[gcr0003]

4 years ago I dug my dads old wheel bow PSE out of the attic, got it restrung and adjusted for me to shoot. My dad is a good bit shorter then myself so the guy at the bow shop extended the draw length on the bow. Not knowing a thing about bows I took the full length arrows that were recommended to me and the unknown draw length and went to shooting.

I measure from the front of my riser to the end of the d loop at full draw on the old pse bow and was at ~30.5 or 30/75"

I shot that bow for two years before buying an Elite from a guy here on aldeer.

The guy I purchased the bow from told me that the draw length was set to 29.5. I have shot this bow for a year with no real issues; though, I would like to be able to shoot each bow using the same draw length.

I have done the thing where you hold the arrow on your chest and reach out as far forward as you can and got 30.5" consistently.
I have done the wingspan (both arms spread wide) and divided by 2.5. Also getting 30.5".

The arrows to the Elite bow were 29" long from the insert to the inside notch of the nocking. The D loop appeared to add ~ .50-.75" which would put me aroung 29.5" (which is what the guy who sold me the bow said it was set up for.

Is the measurement 30.5" pretty close to accurate? Should I take my bow in and have it adjusted to add an inch to the draw length?
If I add an inch to the draw length would I also simply add 1" to my arrow length or is there a simple relation to how much over you draw length your arrow should be?

I am asking this because I would like to have both bows adjusted to a singular draw length before I purchase and cut anymore arrows

Do you shoot the bow(s) well and comfortably? Measurement of your body is more of a starting point than finish line.

Have the arrows long enough to not fall off the rest at minimum. I like to make sure the broadhead is forward of my hand. Again there's room for personal preference.

I do shoot each comfortably enough. I mainly want to have the same draw length for consistency.

Where is the draw length actually measured to and from on the bow?

Horizontal distance from deepest part of the grip to the nocking point plus 1.75 in.

I measure proper draw length by holding my grip-arm out at full length in a shooting position (except hand making a "stop" sign instead of closed grip) and measure to the corner of my mouth, then subtract 1" for my d-loop. For arrow length, I like my broadhead to sit approximately 1" in front of my hand at full draw. To check that, nock an uncut arrow and bring it to full draw. Have a buddy/your wife mark with a sharpie where that is for you, then have arrows cut to match. Don't know if that's standard, but it's what works for me.
