While the shooter in question MAY be able to shoot to a MA level in a 5x5 classifier through practicing the classifier, I would strongly recommend against that path. In my experience (again), the Masters and even Experts who attain those classifications through match bumps and (to a lesser degree) shooting the FULL (72 rd) classifier are MUCH stronger shooters.
The 5x5 classifier (4 strings at 10 yds on a single target) has utility for getting new IDPA shooters an initial classification, but bears little relationship to what it takes to win matches.
