I saw people complaining how long wait times for review of public channel candidates nowadays are - many weeks (8?), months even (what's the official word, avg. wait time this quarter?).

So this seems kind of important - and i am making some assumptions here, like that channels would be generally reviewed in order of submissions (baring urgent patches and so on). That's what i assume, that there is a "queue" - a FIFO variety - where submissions go to wait and be called to a "hearing" by their ordinal number. (Let me know if imagine it way wrong!)

My question is, if while channel waiting for its turn to be reviewed - a new version is ready, or significant bug was found - will submitting new binary send the applicant to the end of the queue for another eight weeks - or can patch-work be done before real review has started w/o losing its "priority date"* ?
