I think people are frequently skipping over this bit:
'We often rearchitect or turn off parts of our scoring in order to keep our system maintainable, clean and understandable.'
What kind of evaluation would potentially muck up a system - age scoring, recip tracking, something like that? Especially when that particular method might anyway have been superseded by another change (for example, random recip link powerhouses might anyway get dinged by some quality factor while real shares between authorities might be worthwhile to score).
