Other reason is s9 can be change from 13500gh to 9200gh in software in under a minute.
A large miner or two or three could have two power prices.
Low price from 8pm to 8am
High price from 8am to 8pm.
So a guy with 1.35 eh could switch to 920ph
With a auto script it would do the whole farm fast.
Take ten farms and that is a 4.3eh switch

Oh yes, thanks, this convinces me! I really forgot about the possibility of different coins (not BSV which I took into regard) using sha256d. And the "switching on/off" also looks logical!
ok here are a few things you need to know
1- Fork.lol shows only BCH(ABC) hashrate , SV has almost the same hash rate so they in total have about 2 to 3 EH ( which is not minimal at all) at the time of typing this
check it here > https://cash.coin.dance/blocks/hashrate
2- There is a tremendous amount of SHA256 hashing power for rent on places like NH , so that power moves very fast between BTC and other Sha256 based coins, many guys who rent the power use some bots to mine the most profitable coin at any given time.
3-there is a good correlation between price and hashrate, seems like some large farms have their circuit breakers connect to some arduino box that triggers off-on based on price ? no solid proof but very possible , i am aware of farms who cash out btc to fiat like instantly so that they don't take any risk should price fall, so it makes sense to instantly turn off the miners once they are not making enough money to pay for power and bring them back on when the price is up to x.
price
hashrate
notice, price drop on 20th, so does hashrate , price spikes on 22nd so does hashrate. they are not 100% correlated but to a good extend they are, you can compare them using these sites.

price > https://www.tradingview.com/symbols/BTCUSD/
there are of course many other factors, but i think these are the strongest.

Of course, I considered this - but the BCH hashrate is minimal compared with BTC, as can be seen just on fork.lol. Moreover, the reward (on the same site) has quite different behaviour compared with the spikes of the hashrate. So my mystery remains 
One possible reason is the movement of hashrate between BTC and BCH depending on profitability.
For example you can take a look at fork.lol and see the big spikes of profitability on both sides....

Hi all,
has anybody some idea why the total hashrate of bitcoin is oscillating so strong? Example from https://fork.lol/pow/hashrate: About 38EH/s on Jan 22, 13:00, and 53 EH/s on Jan 23, 12:00. There are three such huge peaks within four days. 12h averages should not have such statistical deviations, and it is not for the first time.
Miner farms switched off because of power problems (price, supply)? Hardware instabilities? Pool switching?
