Prediction -- How long do you think the electoral vote count will take starting tomorrow?  In other words, when will it be finished?

In 2005, when there was an objection to one state, the count finished at around 5:30 p.m.  In 2017, with Biden shutting down all objections, the count finished before 2:00 p.m.   And, of course, if there are objections to multiple states, there is the issue of whether both houses will want to plow through with an all night session (with two hours of debate and then a vote on each objection) or will recess at some point of the evening and resume the count on Thursday.

So I am looking for guesses as to when the count will finish and your reason for that guess.  (In other words, how many states will be challenged and when/if Congress will break for the day on Wednesday evening -- and any subsequent evenings -- and resume the following day -- and if necessary will they have sessions on Saturday and Sunday.)
