I'm missing something here. You're only going to test one option
at a time ? In that case, I believe results won't mean much,
as in many cases one option may change the usefullness of another.
For instance, in my experiment, the order of quality for
*cmp is 6>2>3 w/o qpel and mv0, but 3>2>6 w/ qpel and mv0.
So testing those 3 separately won't make sense.
