The difference will be the weight of water retained by the brush.

The problem is the humidity in the room and the altitude you are at and the temperature will affect the outcome. You should use distilled water to keep things honest too. (assuming you want to be precise)

Yes! Everything should be performed in a vacuum chamber to eliminate any discrepancies!

That's a good idea, as well. A non-heated take on how they measure moisture content by weight in powder/granulated things like flour, dirt, etc. There can be "Method 1" and "Method 2".

More than one method for some things is good because not everyone will have the same tools at their disposal. I do happen to have a kitchen scale at my disposal that can be switched between different units of measurement. But I don't know anyone else who does.

Also, the trapped evaporation gives a quantifiable means (so some degree) to SEE how much water those natural bristles actually hold on to. Anyone with a synthetic brush can tell you that (especially if it takes a bit longer to shave) you have to add a bit of water to the brush before each pass of lather. That was much less of a concern with my cheapo Chinese made pure badger. The reason: hair absorbs water, whereas plastics do not. Am I still making sense? Lol.

I am still with you......I think!
