The event the ISSF promote and Zooma's club have taken on board is not "bench rest" it is "Rested" and it is certainly not easy. Its an event designed not so much for young beginners, but aimed at keeping older shooters in the sport. Look at the rules as notified by Thirdwheel in the first post, there are pictures in it and you can see what its all about.

It is the biggest branch of shooting sport in Germany and generally in Europe (why the ISSF has climbed onto the band wagon), most rifle manufacturers make rifles specially for this discipline (called auflage in German)

Its a fun event, and having tried it with expert standing and prone shooters who discovered its not easy!

Bench rest is altogether different is run to their own associations rules, and the NSRA bench rest rules are a mystery to every one, not meeting either!
