Cells are subject to aggressive binning – akin to the early days of MOS process. And specs and process capability adhesion in the industry are not as "serious" as they are in the modern, U.S.-led semiconductor industry.

Last time I checked, most manufacturing of semiconductors isn't done in the US... sure, they are leading in design, but the manufacturing is elsewhere.
