Do a search online about the studies that were done on air cart distribution, and that was done by a 3rd party. There system is about the same as concord used years ago, which wasn't bad for its time.
Exactly which studies are you talking about? I believe MB pulse paid PAMI to do one in 2018 on Bourgault and Deere and Bourgault had a CV of around 11%
11% CV isn’t bad for any air system.
