Thanks @hugoabonizio for the siteimprove you linked to !

So that's the developer's responsibility to "clean up" the scores he gets. Ok.

@watzon : Would you be interested in PRs implementing other readability tests listed here ?
Examples :

• Automated Readability Index (ARI)
• Coleman-Liau
• LIX
• SMOG

?

Hmm, we should probably cap the score at 0 and make sure it doesn't go lower. I would definitely be interested in a PR for other types of readability scores as well @rmarronnier

I'll let you decide about capping scores. But FYI, I used the cadmium flesch test on 2000+ GPT generated texts. And the lowest ones got around -600 (less than a dozens) (some Eminem-like lyrics without punctuation). The "garbled" ones (random succession of special characters) got -Nan.
So a cap at -1000 or -2000 should be pretty safe IMO.

ok, one PR per test, let's roll ! ;-)
