Hi AIMster, at one time I had a spreadsheet that tested this. I used the 10,8,5,4,5,8 data, and decided that it was not worth bringing up. Basically if PCIR (Portfolio Control Incrementation Rate) is set to zero, then AIM should behave as a (constant dollar plan). As you increase PCIR you increase the likelihood of getting a second buy, even though the stock price did not change. You could look at PCIR as a dampening factor, the higher percent PCIR is, the less the dampening is, at (100% of the buy), you end up with none stop buying.
I don't think Mr. Lichello did much more testing, after getting it to work, remember he was doing it all by long hand.
Take care,
Clifford
