“The Bottom’s Up Draft Beer Dispensing System is a system that fills a draft beer nine times faster than normal methods.”

“the company claims that stadiums can go from eight beer pourers for every two cashiers, to one beer pourer for every eight”

Eh? It pours 9 times as fast, but you get a 32-fold increase in efficiency? (4 pourers to per cashier to .125 pourers per cashier)?
