TT ratings don't mean squat anyways. When a problem is too hard, I heard you can just refresh the page until you get an easier one without losing rating points.
More than that, there aren't so many TT problems, so simply you'll get the same positions often.
A good memory is enough to achieve a high rating.
whats the point of F5'ing when you will never understand the higher rated problems, thus never improving
