I'll keep track of the cinders I see in our 10 man raid here in case Wowhead continues to not differentiate between difficulties and raid sizes :) Thus this post may be updated between Tuesday and Thursday with new numbers each week. Yay stats.
Week 3 our "staff-getter" was unable to show up one day, hence dashes...
Week 5 our "staff-getter" had some drama and decided not to show up. You guessed it....dashes...
Week 7 the numbers became not accurate to the progress values, which are accurate. How odd... It's possible that "staff-getter 1" went into the alt raid on Week 5 whereupon he net 36 cinders (18 + 18) which evens out the values.
Week 8 "Staff-getter 1" was unable to siphon Essences from Alysrazor and Majordomo. Very interesting...
Week 9 Achievements week, last week of maintaining updates to cinder drop counts. I believe we have successfully established the correct values for the ranges :)

It is becoming apparent from these stats as well as scattered reports of drop counts and difficulties on this page and others, as well as Wowhead data (which does not denote any raid sizes or difficulties) that the following ranges are represented:
