The following are some notes that pertain to NIST's SP 800-90B. These have all been submitted to NIST as comments to SP800-90B, and are thus public.

• For reference, here is NIST's final SP800-90B (a local copy).
• SP800-90B Comments from UL (Version 1.9, dated 20191212).
• Implementation Comments (Version 20191219).
• Aaron Kaufer's Further Improvements for SP 800-90B Tuple Counts (Version 20190410).
• SP800-90B Statistical Changes from the 2016 draft (Version 20180614). Please note, that NIST's Markup of Changes is a better and more authoritative source for most uses.
