Why wouldn't one photograph a reflection target? Based on what you're describing, and another current thread my view is people make this stuff too complicated and the testing conditions, theoretical values etc become too far removed from actual field conditions for the attempted level of "precision" to translate to actual photography. Things like flare get in the way. Not to mention these tests do not typically yield a full H&D curve that plots out to high densities.
