Tumbling with dry media & Simichrome

Hi to all, been lurking for a while now, hope someone can help:

I want to charge some walnut and corn cob with Simichrome, but have
no idea how much to use. Please assume 1lb of media and please suggest
either the weight of Simichrome to use, or inches squeezed from a
small (1.76 ounce) tube.

I don’t measure when charging media I go by adding a small amount
(1/4 oz maybe to start) of paste to media mixing with my hands. The
way I decide if it is charged enough is I grab a hand full of media
if is does not stick to hand then it is to dry if it does than you
are ready to tumble always works for me.
