Good luck getting agreement on those.
But 'what if' situations are very dubious anyway. Whats to say that if he didn't for example drive into Kobayashi in Spa that his engine wouldn't have exploded the next lap? You can count retirements as a raw number, but that's about it.
Aaaaaaand theres the problem with trying to include these stats. You have the Spa 09 incident that included both Button and Hamilton down as being the fault of Grosjean when counted in Buttons stats, but the fault of Hamilton when counted in Hamiltons stats.
Ok, but do you then have to look at the number of overtakes and overtake attempts too. Vettel, for example, had no collisions last year (that I can remember), but thats not because he was great at overtaking without colliding, but was because he spent most of the time out front on his own.
Going any deeper than the simple number of DNF's is a massive can of complicated worms.
What it tells you more than anything though as that in terms of stats both drivers are incredibly close. I doubt any other team pairing over the same period is as close.

not trying to nitpick - but LH is still directly responsible for a lot more of his own DNF's (by making stupid mistakes)
Agreed, but being able to quantify exactly how many is soooo not worth the arguments (again).
As skeeter said that would be argued forever. JB may not have caused a retirement but for instance he stopped Lewis scoring a hat full of points in Canada by not seeing him.
Those sort of stats can be argued all day long
