I may have found a bad discrepancy in Slushpool's reporting... Can you guys cross-check it for me? I'm not happy to say this, and rather than accuse anyone, I'd just like to get some second opinions. If I'm wrong, I ask redditers to politely explain why this discrepancy appears to be happening. After all, maybe it's my math, or logic, or facts missing, etc... But if there is a discrepancy, it could affect major things like payouts, theoretically... and I mean in a major way... retroactive for years.
My concern starts with the average speed per worker of the bitcoin mining pool, on Slushpool.
As I write (12/26/17 Pacific time, around 11pm), Slushpool currently says it is running at 1.587 Eh/s. https://slushpool.com/dashboard/?c=btc
The website also says there are 62810 workers in the pool. I want to calculate the speed per worker. Speed per worker should be expressed in Th/s, so to reduce it to common terms, we need to convert the pool's global Eh/s to Th/s... which means to multiply the Eh/s by 10002...
one thousand, squared.
The speed of Slushpool was 1.587 Eh/s, so we set it up like this: 1.587 * 1000 * 1000 = 1587000 Th/s. †
Now to get from Slush Pool's total Th/s to Slush Pool's average Th/s per worker, divide total by number of workers...
(1587000 th/s) / (62810 workers) = 25.26 Th/s per worker.
So I got the number I was looking for... excellent. You might say "Okay, interesting, so the average worker is mining at 25.26 Th/s. NP. Cool."... But what you SHOULD be doing here is asking HOW ON EARTH ANY WORKER IS MINING AT 25.26 TH/S, and even moreso how THE AVERAGE worker mining on Slush Pool is mining at that speed. The fastest miner on the market is the s9, and it mines at 14 Th/s. So how is the average miner on Slush Pool more so much faster than the very best miner on the market, today? The S9, The BEST MINER on the MARKET, today, is only 56% the speed of the AVERAGE miner on Slush pool.
Now, maybe somebody built a specialized frankenminer in a laboratory... maybe someone uncovreed a secret cache of Spondoolies SP50 miners... which was designed to mine at a whopping 110th/s, for example... but Spondoolies went bankrupt in 2016, and production was halted. Even before then, they didn't make too many sp50's, and they were restricted to special clients.
So... assuming it isn't legacy Spondoolies sp50's doing this mystery hashing, how else can we explain the high h/s on Slush Pool? Maybe someone got really good at overclocking... maybe they cooled the hell out of their miners, so they can run at super fast speeds. Would that really be enough to yield 25.26 Th/s? Is that credible? Is it possible or plausible? ... Even if some miners are achieving that incredibly blazing speed, would the AVERAGE miner be achieving it?
Don't forget about how the AVERAGE includes all these micro miners, as well... misfits like the u3, gridseed orb, blade miner, s1-s5, running in a dorm rooms, etc. There are hobby miners who would pull the average h/s (per miner) on Slush Pool down alot.
So, how is it possible that the pool is running at this speed? Better asked... IS it possible, and if so, how? And if it's not possible, then what are we looking at?
If the pool operator is overstating the total hashing power of the mining pool, then are payouts being reduced according to a false ratio, where the divisor in the ratio is artificially large? The payouts are based on that... they depend on it. So are the payouts on Slush Pool being artificially shrunken? If the total Eh/s of the pool is really much lower than what they say, then I'd have to suspect that it is. But I am absolutely NOT saying for certain that this is what's happening. It's what my suspicious anxiety closet suggests could be happening... but I really don't know. That's why I'm asking you guys to help sort this all out, and explain to me whether these concerns are misguided or not. I'm asking a question, here... not throwing accusations. Frankly I think it is more likely that I've made an error of some kind, either miscalculating or possibly unaware of some vital detail, than that the net's oldest and most respected mining pool is doing something like this. It is very likely there's a good explanation for the apparent discrepancy, but I do not know what it is... so again, I'm asking you, reddit, if you can evaluate this reasoning and comb it for flaws, math errors, weak factual assumptions, and/or whatever else might explain what I'm seeing, or if you can confirm the math and logic framed in the questions I've asked. Thanks everyone, and have a happy new year.

(here is a site with a calculator which goes from E~ to T~. Although it does not have Eh/s and Th/s, you can use Ehenry to get the same mathematical result. https://www.translatorscafe.com/unit-converteen/inductance/5-4/gigahenry-terahenry/
I keep reading that every question about mining setups is replied to with "just buy Bitcoin and hold." Now enough with that answer. If I had $1,000,000 dedicated for a mining setup, not for buying bitcoin, what machines and setups would you recommend? submitted by
