Sam Deduno: King of Fielding Dependent Pitching?

Over the last three seasons, (min 450 IP), Jeremy Hellickson has accumulated 6.8 Fielding dependent wins. FDP wins are calculated based on a pitchers combined ability to limit hard contact on balls in play and strand runners ie. throw strikes from the stretch, limit the running game, etc.
Hellickson's 6.8 FDP wins leads all qualified pitchers, by far. Next closest is Jared Weaver, at 5.4 FDP wins.
Which brings me to Deduno, who in 10 starts has already accumulate 1.0 FDP-wins. 0.3 of which is owed to BIP-wins (ability to induce weak contact on balls in play), and 0.7 wins for stranding runners.
Carry that out over 33 starts, and that is .9 wins due to Deduno's ability to induce weak contact, and 2.4 wins due to his ability to control the run game and pitch well from the stretch. An astounding 3.3 FDP per season, dwarfing Hellickson's 2.3 FDP-wins/season.
Is that sustainable?
It has been speculated that the key to Deduno's success, despite his walk rate, is the difficulty hitters seem to have in hitting his filthy stuff with good wood. But that appears to be a small part of it. Most of his success is in stranding runners.
For comparison, the leader in LOB-wins over the last three years is Ryan Vogelson, with 2.7 LOB-wins combined (.9 / season).
So I think its extremely unlikely that Deduno will continue to overcome his walk rates in the future, although I think like others that his .9 BIP-wins / season (current rate, anyway), is definitely achievable.
So, add it all up, Deduno's current FIP-produced win rate (measure by WAR), is 0.7. Plus 0.9 BIP-wins, plus, say, a conservative sustainable extimate of LOB-wins at 1.0, and you have a pitcher who has a positive value of 2.6 wins total. This places him between Gavin Floyd and Matt Garza, in comparison to pitchers over the last three years, on the RA9-wins leaderboard.
Not the king of FDP, but not in bad company either.
