The very big questions is, what is considered as SEO reaction?
If I update my pages every day, because to update my stock info and my site was lowered simultaneously because a other site was moved above mine by transitional movements.
Is the algo now regarding my site because it was moved down?

How big must the changes be onpage to trigger this algo?
Is it a complete new page redesign. Is it new links added, title change, small word changes?

This algo needs a lot of machine power because every single transitional change would trigger the algo to look at the "moved" sites. This is a circle.
