Any specific days/ frequency for new batches of DM or PPR?

[EFK]

Do we know if there are any specific days for the DMs/PPRs?

For exp: We know ITAs will always be on Friday night/ Saturday, approximately once or twice a month..

Do we have any such trend on the batches of DMs or PPRs? Or do we know their frequency? (for exp: is there a new batch every 10 days... etc..)... or is it all just random?

Thanks
