I don't have any good ideas about the water content, unless you wanna dry a portion and weigh it before and after.
About the vinegar, i'd add none if it has already soaked with vinegar before. Maybe a little splash. I would just use distilled water for the top-up.
How much water you add kinda depends on how you want to proceed.
If you want to strain out the bark and proceed with liquid only (basically doing textbook A/B), i'd add plenty of water (such that it at least covers the bark well, up to double the height of the wet bark in the container). You can reduce it after straining (but before basing) if you want a lower volume for the pulls. If you do add vinegar, do it while the bark is still in and give it some time and heat. There's no point in adding vinegar after straining - on the contrary, it can cause lower yield if you add too much, because the acid and the base will create a buffer and trap some of the alkaloids in solution. The acidification step is mostly there to improve/accelerate the migration of the alkaloids from the bark into the water. And to make sure all the alkaloids are in salt form, which they should already be in the plant afaik.
If you want to basify and pull with the bark still in there (making it STB or rather ATB since there was acidification first), you simply add the amount of water that gives you the consistency you desire. It's possible to work with consistencies from thick paste to thin soup. You can add a bit of vinegar if you like, or not. Personally i like both thick paste and thin soup, but not anything in between.
With a thick paste, the naphtha kinda runs over/through it during mixing and then flows back out without picking up much bark or any water (the bark paste tends to keep a significant portion of the solvent though). Idk if this is an option with lye, everytime i went this route i used calcium hydroxide as the base, which helps it be extra thick.
With a thin soup, the liquids usually separate quite well and there's not much emulsion, unless you overdo the agitation. The naphtha mostly has contact with the water, not so much with the bark, and you should be able to get nearly all your solvent back out.
With runny paste or thick soup, imo you combine the bad aspects of the two. The bark will swallow a lot of solvent, and it's easy to produce tough emulsions. Maybe that's just me.
If you do get nasty emulsions, if nothing else works, filtering them should do the trick.

Is there any harm in adding in extra lye to the mix when there is already naptha in it?
I can still use the naptha that i did the previous pull with? It has like a green color to it.
If the mixture is too heavy in bark is that why the naptha is not pulling any DMT out?
I'm not sure what pH is really required. I just go by the color change - after adding enough lye the solution turns black, with creamy bits for a short while and then all black-ish. I add like 10% more for good measure at that point.
I don't think there's harm in adding more lye after the naptha is already in. You add it as an aqueous solution, which doesn't mix with the naphtha.
Yes you can (and should) reuse naphtha from previous pulls. It might even still hold some DMT from those... Green color sounds strange though, it should normally be somewhere between clear and yellow/amber.
I don't think "too much bark" would cause the naphtha to not pull DMT.
My guesses for possible causes of low yield are:
- you got most of the alkaloids in the first run already
- you didn't basify enough, possibly because you acidified too much
- you didn't agitate/mix the soup/bark/naphtha mixture enough, and/or the naphtha was too cold during the pull
- the bark might have soaked up part of the naphtha, including the DMT it contains
- your freezer doesn't go low enough, or you didn't freeze for long enough for complete precipitation. Or you used too much naphtha and have to evaporate part of it to get sufficient saturation, then freeze again.
