I mean there's only 17 trades since 1960, all 100%, but again some of these trades hold for 7 and 8 years, while most are at least 2 or 3, to me I've always liked the name 'paint dry' but it really is like watching paint dry - unless you don't trade the markets at all, I don't see how it would be useful to anyone here.  It's still better than just buying and holding as it gives some protection for major bear markets (except when you have fast hard corrections that are over within a month) but keeps you out of major bear markets that last 1 and 2 years, that said those are rare and for me this is a cool system like chart but not really practical for folks here - maybe for some of your friends who will never trade, but want something that rarely gives a signal
