That was my first question and it was also asked of swiftech. Their answer was the graph is independant on pumping power and it doesn't make a difference.
I do however think there is a difference regarding the jet like action you get from a 3/8" barb vs. a 1/2". Could be one of those little details that slipped into the test because it was in swiftechs favor. They also hinted around about what sounds like a nozzle of sorts in the works.
I don't see why else they would use 3/8" barbs when the main customer preference would be 1/2" unless somehow it favored the results their way.
