Yes, I know some accountants as well, as well as bookkeepers who have to do adjustments for things like 'timecards' and punching-in and -out: there's all sorts of adjusting that needs to be made.
But any "mistakes" that are made are simply corrected the next reporting period (whether that's monthly, fortnightly, weekly, or daily) in this more-frequent proposal.
The 'crunches' that occur at quarter/period-end are there because there is so much attention put on those reports because they're so infrequent. If the sampling rate is higher then errors are corrected that much sooner.
The reports are generated on the books in the state that they currently are in on a monthly/fortnightly/weekly/daily basis, and any adjustments will be "fixed" in the next reporting period. The reason why there's so much pressure to get them "correct" now is because of the (relatively) infrequent reporting. If you know that things will be 'sorted out' in a fortnight (two weeks), or whatever, there's less pressure now to get them "right".
There will be an expectation of less perfecttion and more corrections and better 'smoothing' due to the higher 'sampling rate'.
