No, it's not a "down under" thing. There are a lot of Aussies that are running our kits, and also an Australian Pro Stock team running our custom rockers with the stand corrections. It's strictly a Bewy thing.
Bewy likes to reference stuff he reads, and then make it conform to his own ideas. It's like the Smokey Yunick references that he misstated in a previous thread, and he likes to reference Circle Track Magazine a lot. Well, here's a link for a Circle Track article about rocker geometry.
Rocker Arm Geometry And Valvetrain Alignment (motortrend.com)
It completely disagrees with Bewy's version of rocker geometry, and even shows examples of how centering the pattern can be very detrimental. But, as usual, Bewy will likely twist and spin everything to support his viewpoint, and claim he is still correct. It's sad really, because I don't think he is stupid, but simply refuses to learn something new. Either that, or he is just to stubborn to admit being incorrect.
By the way Bewy, this is Rat's defense, and a very good one at that. Also, it's my busiest time of year, so I won't be getting into a long drawn out argument. I have to serve my customers with my time.
