I did a similar thing back in the early 2010s. I heard all these myths about stand developing, and the only one that was provably true was that stand developing meant you didn't need to know an exact development time for a film (good for found or unlabelled film), and that by extension you could develop different films together at the same time (if you had a big enough tank).
"Stand developing means you can shoot multiple EI on the same roll" was patently bullshit, and the first thing I proved wrong. I don't know how people got away with claiming that. I've not seen it written anywhere for about a decade, so it looks like that's been thoroughly debunked.
But in all honesty, I've never had better results with stand developing than I have with proper agitation methods. And when you factor in inconsistencies due to temperature fluctuations and the ever-present threat of streaking... it's just not worth the time, as far as I'm concerned.
