Adam, I forgot to answer your other question:
do you trade your LD-AIM programs in taxable or tax deferred accounts?
Always inside traditional IRA's.
I've never run any AIM program in a taxable account.
If I did, then I'd probably run wider settings (trades less often) and larger absolute program size (larger trade size) to take advantage of Long Term versus Short Term Cap Gains rates (even though for Tax purposes I'd use FIFO) and less commission. Of course everything else being equal, the diversification would be less than what I proposed (fewer programs).
Hope this helps.
