question about SINAD “charts”

first: —
since I am not a native english speaker:
is “SINAD” used here in the exactly same meaning than “THD+N”

second: —

but this is a picture (screenshot ?) only (that is different in every review),
is this chart hosted somewhere (link ?) as a “master”, and updated every time a new review is done ?

then there is this “Amplifier SINAD list”
done by
(or does it take Amirs data and additional much more (unvalidated) sources e.g. from the manfacturers ?)

since I am new here at ASR I have questions about the SINAD charts (for AMPs) that exists here …first: —since I am not a native english speaker:is “SINAD” used here in the exactly same meaning than “THD+N”second: — @amirm uses this kind of chart https://www.audiosciencereview.com/…-d-monobloc-amplifier-review-2023-png.257210/ but this is a picture (screenshot ?) only (that is different in every review),is this chart hosted somewhere (link ?) as a “master”, and updated every time a new review is done ?then there is this “Amplifier SINAD list” https://docs.google.com/spreadsheets/d/1ZlTOYxmPs938gqHjtDABkWS-MApu7uJjzIGnJ2Elm6Y/ done by @Matias , is this related somehow to Amirs chart ?(or does it take Amirs data and additional much more (unvalidated) sources e.g. from the manfacturers ?)
