[Vendor] HJ — small operation, honest about lead times, that is worth something
Title is the summary — HJ — small operation, honest about lead times, that is worth something — and the detail is below in the order it happened. Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find. Kept a spreadsheet of quoted…

Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.
