You want the volume that you had in the pot after you removed the grains/squeezed the bag. You shouldn't include the volume lost to the grains during the mash.

Honey is generally 36-42 PPG, meaning one pound will raise the gravity in one gallon sort by 36-42 gravity points.

For your volume, multiply the volume of honey x36ish and divide by your post boil volume (before loses), to get how many gravity points the honey contributed.

In which pot, the initial mash or when I pull the grains from the sparge and then combine?

What I'm thinking you mean is I should get the volume of water after the grains are removed from the sparge water and the mash is poured into that. What ever that size is will be my volume which I can guesstimate from the level it fills in the pot and use that same moment to get the gravity from that now combined two pots which is my wort. Yea?

Yes, you want the volume after you've removed the grains and before you start the boil.

Typically you calculate your efficiency prior to the boil once your preboil volume is hit (your SG). Your preboil volume is important when calculating brewhouse efficiency as too little wort will typically make your efficiency go up (inaccurately).

On a side note in regards to the honey, I'd keep adding at flameout as most honey is not pasteurized.

*wipes sweat from brow*

Ok, so I'll lower the volume to my estimated volume at that point and measure the OG. Thank you so much afr0byte!
