I'm also surprised that no one has attempted it. For one thing, there are always "theories in the air" about what intonation scheme musicians actually use (Pythagorean vs. equal- tempered, etc.) However, one thing to keep in mind is that most musical instruments don't produce absolutely constant F0's. There is always some variation, even when there is no vibrato. This could have a big effect on DL's. Also, there is the problem of how F0 should be measured when it is time-varying.
