Couple of small comments inline.
There is the larger question of performance, but that's not going to be worse than what we had before. Since this is now in the reporting plugin it is probably worth checking how it performs in staging/prod environments before we action on it.

I've made changes as requested. During dev I tested this with 5,314,070 preprint access records and it was reasonably fast. Unfortunately changing to filter by __date seems to have caused a slight performance hit, it takes 2116.88ms for the query now and it was previously < 1000ms.

Just a minor suggestion regarding the new DateForm to make usage a bit cleaner.

There is also the question of performance, but I think we'll need to get results from a real system before we can optimize for performance.
