Yes, I do that sometimes too - if there is a statement saying "spouse:
X" on wikidata, and statement in Freebase saying the same but with the
start date, or the Freebase one has more precise date than the Wikidata
one, such as full date instead of just year, I will modify the original
statement and reject the Freebase one.

I filed a bug report for this yesterday: https://github.com/google/primarysources/issues/73
I'll add the information about more precise qualifiers, since I didn't address that part.
 
I'm not sure this is the best
practice with regard to tracking numbers but it's easiest and even if my
personal numbers do not matter too much I imagine other people do this
too. So rejection does not really mean the data was not entered - it may
mean it was entered in a different way. Sometimes also while the data is
already there, the reference is not, so the reference gets added.

Even if you don't care about your personal numbers, I'd argue that not being able to track the quality of data sources feeding the Primary Sources tool is an issue.  It's valuable to not only measure quality for entire data sets, but also for particular slices of them since data sources, at least large ones like Freebase, are rarely homogenous in quality.

It's also clearly an issue that the tool is so awkward that people are working around it instead of having it help them.
