"The goal is zero, so however we get there is fantastic!"

I very much agree. Sometimes people say one tapering scheme is better than another one. There is no scientific proven method of tapering off prednisone. The doctor in the following video says there isn't any "gold standard" for tapering off prednisone.

I think the same can be said for the use of "steroid sparing" medications. I don't think there is any way to predict which one may or may not work well until someone tries the medication to see what works or not. The goal remains the same.
