Another possibility is that you have a high risk tolerance as well as an uncommon knack for this sort of thing that most people don’t have.
In total, I did this with about 40 different farms. There was a time when there were several new ones every day. For a while it was pretty much a 24/7 job as maximizing apy required constantly jumping to some new hype. I was constantly afraid of depositing into a contract that would allow the owner to steal everything, but the worst I noticed were locking bugs + two contracts that allowed the owner to mint infinite tokens (of these two, only one used it to clean the liquidity pool).
The list of farms in that reddit post is obsolete (I think only sushiswap is still running, but with low roi), in general this particular way of making money has run its course.
There is a line from a movie ...

So yes, it is crazy and complex and difficult, but the rewards are vast for those that dare enter the world.
Timing markets at the hour level is fraught with risk and cannot generally be done without information not known to the broader market.
A major disservice, doubly so in a risky space like cryptocurrency and on a public forum. This really just makes the space seem even less trustworthy.
Ding ding. Which is why returns won't last as the information asymmetry curve is flattened.
