Clive, thank you for your thorough reply. The people here are very helpful. I am trying the system with 3X ETF's and am using the PCA software. It gives you various settings so some tweaking is certainly possible.
A yearly rebalanced blend of stocks and bonds (Couch Potato) might produce something like that shown in the third column.
An AIM style that averages 50/50 might produce something like the 4th column, whilst a 64/33 like AIM average might produce the 5th column results. Better than Buy-and-Hold in compound average returns (despite having a lower simple yearly average) arising out of the lower standard deviation (same or better return for less risk).
This of course is highly subjective, but I think you'll get the general idea.
Best. Clive.
PS: Ahhh! I've tried realigning the column values a few times using the update message option. But each time the changes seem to make things even worse. Given up trying!
