I'm really surprised that no one has any comment on this. It's very interesting to me that sites seemed to be ranked without certain filters or without certain penalties on a CSE. It could be a good diagnostic tool.
Imagine you had a #5 ranking and it fell to #15. How would you know if the algo just changed the way you are ranked, or if some kind of a penalty/filter was applied? If things are the way they seem to be, you could check your ranking on a wide ranging CSE like this - and see if you are at #5 (penalty/filter) or #15 (ranking change.)
