Actually after I reread your post more carefully, I think these are very important observations. Good food for thought. Thanks for sharing. I am happy for you. Regards,
Actually what you did was remove all the synthetic nonsense and revert to a 'natural' algorithm. Most of the time the problem with that is it requires contextual analysis which humans are 240,000 times better at than computers which skews to discretionary. Congratulations on making it work, however we have been in QE for almost a decade so be careful that a new context is not around the corner. A simple algorithm allows you to adapt up to 100x faster than synthetic based algorithms which is what the majority use. Good job.
