We use the baseline heavily. Therefore we use phpstan all the time with phpstan analyze --generate-baseline.
When there happens to be an error that prohibits generating the baseline you get something like this:

 [WARNING] Baseline generated with 17184 errors. Some errors could not be put into baseline. Re-run PHPStan and fix them. 

As the error number already suggests this can take some time on our code base ;) In this case I would expect to see the errors that prevent baseline generatoin (so no phpstan rule errors!) which you get when running without --generate-baseline (like Class Foo\Bar was not found while trying to analyse it - autoloading is probably not configured properly.)
