I reckon that it is not working with Tatum. I maybe wrong but his bikes / setup do not seem right. Tonight in one race that he was in a good position as he came out of the bend but two riders just zoomed by on the straight and were a few bikes length infront by the next bend. There just seems to be no speed in his bikes. I think that he is using the same tuner (Marcel Gerhard) that Tatum used when he won his World Long track titles. Maybe he needs to try other tuners instead of being brainwashed by Tatum. It is possible to compete with skill on the smaller tracks but on the big track tonight it was vital to have a good setup.
