That article is about an earlier version of Rocksim - but Openrocket is supposed to have the same issue: it calculates the amount of base drag ok, but doesn't position it correctly.

I've also used it to convince myself that certain squat rockets would be okay to fly.

From a discussion over on the Forum That Shall Not Be Named (I don't have a link handy) the general feel was that the hack could always be applied, no matter the length of the rocket - but that as the L goes up, it's a smaller and smaller fraction of the overall forces. By 10:1, it's negligible.
