and the 1 piece has the ability to skew the luck easier.
And they have the ability to also increase the luck to ridiculous levels, too, because that's how luck works.
Of course the 350k could be done you just have to employ more people, you just have to have a lot of MW available for god knows what reason, you have to have extra racks at hand, again why would, and spend a ton of $ to do that as fast as possible for, what really? A extra week of mining?
The reason why I don't believe in it being possible is because I see all those press release from Mara, Riot, Hut8 and if you look at the rate they put in new gear despite having it in order you will see they barely manage to bring each of them 1-2 exahash online constantly, to think that they would get their gear at the same time and decided all of them to play like this and keep the s19 running for exactly the same time, this to me sounds like a possibility just as high of getting 1 extra block for the 6 you mine usually without doing anything extra.
As mikey said above, a combination of luck, extra gear delivered, some farm testing a setup, a farm maybe going down for maintenance as we speak yes, but just one single factor, I find it hard to believe!
Pace has gone up a bit:
Are you going to do this overnight? No, it will be a gradual process that will last a few days or weeks.
Yup, weeks is the thing, it just doesn't happen in two weeks, on/off.
Besides, the whole renovation thing, let's assume you have 10 000 gears , you plan on giving away 3000 and replacing them with 3000 new ones, why would that company had the space, racks, cables, transformers, cooling already in place for 3000 extra gear? When you renovate something you don't have already things set up in place and working for extra 20 or 25% of capacity.
