Average return is a metric, but it's not the only one. If you really want the biggest possible CAGR and don't care at all about volatility, you won't beat a 100% stocks allocation.

Browne allocation's Sharpe ratio (0.67) is better than yours' (0.60). They serve different purposes and cater to different investors.

I personally wouldn't use Browne's because I'm still young(ish) and have a very, very stable income and will get a pension from my government, so I can stomach the volatility and better take the best average return. But if I were a freelance of some sort in my late fifties or older, I'd get closer to Browne's allocation.
