Noted.  The key to improving on an all weather portfolio is knowing when to rebalance back to the orig allocations and that is when technical analysis comes in.  So if Matt has a supercharged system for these uncorrelated assets, the return should be much improved.  I have a version of the permanent portfolio and have improved the returns over just a simple thoughtless yearly or quarterly rebalancing.  I rebalance when prices are stretched to the upside or downside based on std deviation over bollinger bands.
