@jdecool IMHO there's no "bad" number, the important thing is to get that number gradually down.
In fact, I suggest to use the baseline to raise the level immediately to 7, and start from there, instead of raising the level gradually.
Same for PHPStan upgrades: better to upgrade immediately than to be stuck because you have too many new errors.
@alessandrolai Agree. There's no judgement.
Just want to have an idea of numbers :)
