Would you measure Vitamin C with teaspoons to get long-lasting dev?

They didn't normally compress the heaping measure first. Poured a small bowl full, then just dipped
and struck it off clean.

I first tried this without compressing, and although measurements were repeatable enough, ratios of values from my 1/4-, 1/2- and 1-teaspoon spoons were farther from 2.0 than I liked. Also, tapping the spoon before striking would cause the powder to compact some, reducing repeatability. Compressing fixed both.

Yes, that's why I got an Ohaus triple-beam balance, ha!

Normally the uncompressed measure was good enough for me with very fine powders.

Even with the powder you have to be careful. For example, this one is vitamin c powder, but it is buffered vitamin c.

The buffering agents they use are calcium, magnesium, etc. to help buffer its acidity. Might be good for the body, but buffering the acid is not beneficial for developing.
 
While it is easy mix up a few chemicals that will produce an image formulating a useful developer is not an easy task. The two chemists who developed the Xtol formula worked for a year before they felt confident enough to present their research to Kodak. Even then much more research was needed to produce a final product. The question therefore becomes Are you confident enough that you can produce a reliable developer that you would use on your precious negatives?
