MD/PhD —> Post-Doc (skip residency)?

[BiggiePow]

How many MD/PhD students decide to go into a post-docc rather than a research residency, or regular residency? Of those of you who chose regular residency, but plan to do a post-doc, too, what is your rationale? How does Step 1 score influence applications for post-docc or research residency?
Thanks!

The last dataset I know of this is from 2010

Are MD–PhD Programs Meeting Their Goals? An Analysis of Career Choices Made by Graduates of 24 MD–PhD Programs

Which shows that 95% of MD/PhD graduates choose to go to residency. Only 5% did postdocs while foregoing residency.
