I really think that after the first two/three years there should be a system converting PhD students to an official researcher title, which is what they essentially are. Credit hours for thesis research, most of which is publishable and usually for some grant, is just BS, and even worse it helps justify the fact that one must work 20 hours per week while spending extra unpaid time for fulfilling the thesis research credit.
