Does the amount of bac water actually change anything or is it just about easier math
I have always just used 1ml out of habit because it keeps the numbers simple in my head. Wondering if changing how much liquid I put in actually impacts anything or if people just use more to make drawing smaller doses less fiddly.
Know something that helps?

I stress way too much about exact volumes and ending up with weird decimals on the syringe. For my nad+ vials I ended up going up to 4ml minimum just so I could actually measure the units without squinting at the lines. It doesn't change what is in the glass, it just gives me more room for error when my hands are shaking.
I map everything out in a spreadsheet before I touch a vial so I don't mess up the proportions. With smaller doses like tesa or cjc I usually use 2ml to make the math straightforward. More liquid just means a slightly larger volume to draw, which works better for me personally.
The amount of bacteriostatic water you add is a dilution choice rather than a strength choice, as explained in the reconstitution basics entry in the app's Library. Adding more water does not change the amount of peptide in the vial; it only spreads it through more liquid, which can make smaller doses easier and less fiddly to measure accurately.
As the dose math lesson notes, the amount of water sets the concentration, or how much peptide is in each millilitre, which then determines how many syringe units you need to draw for your target. You do not have to work this out by hand, as the Peptmate app's Quick Calculator does the arithmetic for you once you enter your vial amount and water volume.
