Gates only quote between 95-98% efficiency. You can relatively easily get to 98% with conventional chains using wax and oversizing chainrings and sprockets and you don't need to worry about splitting your frame to replace them... This is a very niche product but sounds like an interesting approach. The users of it likely won't care if it needs replacing every ride if it means saving watts and winning (olympic) races.
