Agree with score clarity being non-existent. This week i ran layers 12 with a guild group - skoldus was a pretty fast and smooth run, mort'regar was just painful (constantly over par time, multiple deaths).
Ended with 180something in skoldus, and 217 in mort'regar. We still don't know how, and it's impossibile to know what to prioritize other than following general guidelines. Also, we killed the 5 floor vendor, just to discover that you find him deaf into the adamant vaults. It was just a rollercoaster.
