I don't know if the JAG has the numbers for that.
Having gone through the system myself as a former CO, a lot of burden was put into it when it was a summary trial, a very legal mechanism. Commanding officers have a qualification for it, but there's no way for anybody to be...unless you're a lawyer.
What this does is put that complexity in the legal system where it needs to be, with the experts, and allows for the discipline piece to be kind of managed.
I don't have the exact numbers, but the point is that this will speed up the process and allow for even the bigger cases to move faster.
JAG, can you add to that?
