OD is tied to driving. JR, I'm not too sure, but I think it's tied to JS/DR as well, which is tied to 1 on 1 training. So it's false that they're not tied to any elastic effect.
Since it's OD and JR, what's the DR level of your trainee? Are you training from scratch or is your player already a work in progress? Also, do you have any idea what level do you want to advance your players to? If you at least share where you want to start from, and what you want to aim, you would be able to get better advice. If not, we're just gonna assume you want to train players like normal.
