However, the B18C5 (Type R motor) is likey to make much smaller improvements as that thing is basically built to the hilt from the factory.
See my above comments...those factors are from an early version that was written before my time.
I'm inferring here that the reason those factors came to play is because, at the time, the big bad boys of IT were teh BMW E36, and the CRX in ITA. Both cars were unique in their ability to exceed factory rated hp by a significant amount, but it wasn't due to architecture. But, I think the authors of that document were reacting to those two cars, and that Process was the result. SOP hasn't followed those recommendations for years.
