Research shows that if you do back to back rotations in august and september, you will fail to match. Interestingly, if you do back to back rotations in September and then august, you are assured a spot in the match. This requires time warping and has been successfully employed on numerous occasions (unpublished results using unsanctioned technology).
Another technique which has been employed successfully on at least one occasion is the Wyclef Jean approach. This simply involves you claiming that you'll be gone til november, and unable to complete rotations until after that time. Conveniently, this is usually too late to do a rotation, but since you've employed this powerful technique (only available to a select few), you're essentially assured a spot, based mostly on bravado. This allows avoidance of an actual derm rotation (ick!) while still matching. Once you've matched you can avoid doing any derm at all, but this is somewhat difficult. I will provide details in another post. The first step is matching.
