If you're a competitive applicant, chances are you're going to match in the top 2 or 3 of your rank list, and among those, most likely your top choice. So really only need to go on half a dozen interviews at the most.
However by the time you're faced with making a decision on which interviews to decline, you've likely already been on a few early interviews which might not be your top choice programs. And then some quality programs likely won't send out interview offers until mid-late July, at which time you've been on a few more, so you're left with going on a dozen interviews all across the country unless you are willing to turn down offers from big names.
The match is a good program but it has its drawbacks.
