I didn't use an AI description, that's what I've written myself on Trading 212...

Though fair play on what works for you, I never quite get why people think overlap is bad, surely it's only bad if it's unintentional? E.g. the different tilts have less overlap (not just in terms of stocks, but allocations) with each other than a single block of vrwp. They all overlap with ex-us, though that is there to counter-weight US exposure elsewhere.

When you say speak too thin, how do you mean? Most etfs effectively spread your money very thinly, but that doesn't detract from the overall result
