Sage, are you referring to the example required by 226.5b(5)(iii)? If so, you're correct, you use a recent APR (per footnote 10c: "the most recent rate provided in the historical example described in paragraph (d)(12)(xi) of this section or a rate that has been in effect under the plan since the date of the most recent rate in the table.")
I don't see it as misleading, since you also show (under 226.5b(x)) the minimum payment that would be in effect at the maximum possible APR.
