Yes, I know what you mean but I've done similar things in the past, taking a strategy for my own and changing it to the point where it just isn't as profitable (read: lost money while the author continued to earn money).
I think I may have slightly de-railed the train, & for that I apologize.
This is a pretty neat thread & on reflection, ought to remain honest to the original guidelines for exactly the reasons you've highlighted.
Sorry for steering the content off course folks.
Keep the faith
