Rebecca, that is an interesting concept.
I never heard of "proofing time" and Mr. Google may not have heard of that either.
I have a room that is actually my laundry room that I call my equipment room because it has a lot of equipment running that keeps it hot in the summer and warm in the winter.
That is where I dehydrate things, mostly herbs.
Usually, after I feel the herbs are dry
enough I put them in a glass jar without a lid. So far I have not had any problems.
Though I can understand your concept for beginners.
Also, everyone might want to consider like you mentioned there are variables. Warm weather, cold weather, humidity, etc. Even how you are doing the dehydrating. Like me just using a room, using an
oven, using a dehydrator, or even outside in the sun, etc.
