There are too many varibles beyond one's control.

Some have been completely taken aback at my purchasing non-commercial powders and using them. But what I DO use has reference data or a starting point for comparative purposes. The supplier has information "use XYZ data as a starting point, reduce by 10%" etc., etc.

From my perspective I'm more conservative than any published manual. I work with what I'm given using my specific application (far beyond the control of publishers), go slow and incrementally, watching for changes, and I usually also shoot over a chronograph looking for odd things. How can that be bad? You cannot literally "share" data as every individual application is different. You have to "work up" your own, from base information.

Even commercial powders are made in large "lots" that I have seen have variations and not behave as the published manuals list. Every new can of powder, even the same type, I approach with caution and do not take for granted if it's a different lot. Sometimes a listed combination just does not work out well and must be scrapped. I don't have all the answers but I learn something new everyday.
