Absolute bullshit. Though, I guess it doesn't measure accents idioms. The referenced paper seems to be using this database: https://www.hcias.uni-heidelberg.de/en/research-at-the-hcias...

And even that data is kind of suspect, based on a simple glimpse at the screenshot, which shows idioms for "ISN'T IT?". Colombians definitely would say all of the following, unlike shown in the table:

  A cada quien le va según quiere Dios, ____
  - cierto?
  - no?
  - o no?
  - si o no?

And actually would probably not say "si?" as shown. "Verdad?" might be heard, but maybe an older generation.
