Using Ocroft style on Doug's monthly data (to 2014 older spreadsheet) i.e. monitor a monthly AIM on paper and only update your actual AIM/buy trades after the prior months paper traded AIM indicated a buy trade but the current paper-traded AIM review had no trade being flagged.
Just 5 buy trades since 2000 (red dots).
Sales can be made as and when they're indicated.
If you only "reviewed" buy trades at those time points it seems by eye to have performed a reasonable job of the 2000 - 2014 history. But as the first red dot suggests, can have you trading early into a more prolonged down-run.
