I think it really depends on the person and how long you've been on the steroids.
I am having a TERRIBLE time tapering, myself, so I have been going excruciatingly slowly only to have to go back up--devastating. Seriously.
However, if you haven't been on them that long, you can probably do something like
A week each
Then taper by 5's for a week each until 10, then either continue or go a little slower, depending how you're doing.
