mikeywith, from my personal point of view as you said about S9, those are the best miners from Bitmain and that tool was released after the S9 was first released. However, taking into consideration the connections this provider may have and more specifically inside Bitmain, the only fact that they are developing a software update to cover something that hasn't even hit the markets yet, thus nobody should know how those series will perform, it tells me they know something about it or may have a beforehand information and want to be ready when that happens, specially the Chinese.
