I think there's something up with the GTX 1070ti testing in this article, your Performance Rating for the card is only 2% higher than the GTX 1070, and for sure the GTX 1070ti is faster than that - in fact it's actually closer to the GTX 1080 in performance. I noticed that your Firestrike Graphics Score for the 1070ti was only 18219, only 2% higher than the GTX 1070, something is definitely wrong with that score, it's very low, should be substantially higher - no GTX 1070, even a factory overclocked third party model will be faster than a GTX 1070ti unless you manually overclock the GTX 1070 - the performance shown for the GTX 1070ti is too low in this article, it's way lower than other review sites I've seen, I think something was up with the testing & or testing system that would explain the low performance of the GTX 1070ti.
