three years of normal threads, summarised so you do not have to read them

Material has been consistent. Communication has not. Shipping has varied by about 20 days on nominally the same lane, which matters more in summer than in February.
The independent number came back 98.4% against a claimed 97.2%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.
Batch number is in the comments. Ask if you want the method.
best — the order this archive was captured in
The what is question took me three weeks to understand. Wiki explained it eventually.
