According to mononaut, there were only 3 stale blocks in the last 5000 mined blocks, and they weren't caused by below 1 sat/vByte transactions. mononaut concludes that it made sense to lower the minimum fee rates. The miners earned a bit more in fees without increasing the average number of stale blocks.
Since some changes that occurred in the network in 2017 or 2018 (I don't remember anymore), the probability of obsolete blocks is very low. Therefore, when it happens, it has little to do with transactions.
I think he only considered the difference between what the miners earned
That kinda makes sense, it shows miners who don't mine <1 sat/vbyte what they're missing.
Exact.
It reminds us of those people who don't bend down when they see coins of small value on the ground. But this ground is full of these coins, but as they don't want to go down, they will lose a lot of money.
