Which is accurate?
Your miner status page is your company portal, where you log in and they tell you, your salary is going to x, the pool page is your bank account, it's the actual $$ you are going to get, It's a funny analogy but whom would you trust more?
It's possible that the status page on that firmware is broken, but it doesn't matter, always check the status on the pool page, if your daily hashrate is within a reasonable range of 1-2% in the span of a few days then you are good.
if your hashrate is 100th, idealy it would show as 98th on the pool (- the 2% fee of BOs+) so anything in that 98th range +-1-2% would indicate an overall "healthy" mining.
I've been trying it for about two years, I usually have an S19, also with 6 s19 and 750Th/s full months.
During this time those doubts arise, I continue with everyone in Viabtc or I try my luck in ckpool, if I find a block I would get what I would have to be at least 15 years mining in viabtc, of course, if they do not find a block I do not recover the investment.... A complicated dilemma to fear clear
