Hashaltcoin Blackminer F1 Ultra - updated FPGA miner

hashaltcoin_blackminer_F1_ultraHashaltcoin announced a new FPGA miner model called Blackminer F1 Ultra, which, according to the developer, is 20% faster than the previous Blackminer F1 + model. The cost of new items is 2000USD with a shipment date of December 25, 2019. If we compare the declared hashrate of the new and previous models, then the benefits of the Ultra model are not reflected in the hashrate of 20%, and on the contrary, a lower hashrate is declared for the newer model. Obviously, a mistake crept in somewhere on the site, but what exactly the developers made a mistake in filling out information about the new product is most likely to be clarified only after the start of sales.
