Best is multivariate testing where you not only change one parameter (the 25-25-25-25 allocation) but more than one parameter at the same time including the distribution of the stocks, bonds, cash and metals portfolio and the rebalancing bands or timings as well.

My suggestion: automatically reduce the size of charts too large to fit a normal screen - normal pixel width for a full web page is 960 pixels - it is really annoying to scroll for example this thread http://gyroscopicinvesting.com/forum/http://77.104.139.218/~gyroscop/phpBB3/viewtopic.php?t=7 horiz...
