I am also having a skype chat with Sam - my calculations are fairly rough and based on setting crickets up in plastic containers - Sam has said that he will take any info I have and combine it with yours and his to come up with a blueprint
I had a chat with Sam, who's been super useful. He's more focused on mealworm though. I'd be interested into any info you might be able to share about crickets. Here's my email firstname.lastname@example.org - happy to chat!
