SO by my calculations I quote, I can produce roughly 240 babies per month(60/week) per rack.

does this sounds like a good basis to draw conclusions from?

This is based on an established rack that is producing, not 5 rats thrown together and demanding 60 babies within 30 days.(although in theory they should produce that much or more)
With your setup you do not have the proper space for 1.4 in every tub. You need to separate pregos and moms with babies from the breeding group. Also there needs to be a tub for weaners to grow in. Lastly you need to give mom a rest for at least 2 weeks before she gets pregnant again. A good source for how to set up is RDR's rat barn vids on Youtube. Sorry but I'm not savy enough to provide a link to his site. But watch the vids to learn. Also a good ratio is 2 to 3 rats breeding for every snake you feed.
