To be fair, it's simply a larger chassis. The hashboards in the N+ are the same, they are likely trying to liquidate useless inventory faster. Any return on those boards is better than just scrapping them, so they will do whatever is necessary to sell.

It's not as if Baikal cares anyway, the fact that they had minimum of 5 months of secret mining is indisputable. The earliest mining date I was able to independently confirm was on September 3rd last year, and they operated almost continuously until March 11th. Thanks to cooperation from the administrators at one XMR pool, I confirmed Baikal fetched 3605 XMR between December 11th and March 11th. In addition to mining at this XMR pool, we know they used Nicehash sometimes, as well as some ETN pool that does not exist anymore. Since we had to rely on the characteristics of flash memory to glean this knowledge, there's a chance we're only just scraping the surface of their secret rewards.

PinIdea did the same thing too. After analyzing the clues they left behind the earliest confirmed date for the RR-200 submitting valid CN work was September 15th. They used their own pool though, so no clues to the scale of their operation remain. But based on how early they had a working device, it's safe to say they they too had a small farm for sure.
