Would be nice to see clan records there and it is not easy to calculate them.
I can do that but I'm not exactly sure what it would represent. What do you see it as representing?
I think number of clans at time X vs time Y could be a factor that might distort whatever this ranking is supposed to represent. It definitely could not be used to say Clan A can beat Clan B now - and I'm not sure it would be a reliable indicator that Clan A in their heyday could beat Clan B in their heyday ("heyday" meaning the time that the clan performed its best) due to this possible distortion caused by total number of clans at any given time.
How does total number of clans affect the highest rating achievable at that time? If there are only two clans, and the top clan beats the other clan at 75% win margin, the two clans would come to an equilibrium of 1200 and 800. This would happen no matter how good the two clans are, as long as the better clan always wins at 75% win rate. Who knows, maybe once there are 5 clans, this is not so much of an issue, but someone would need to examine this before drawing any conclusions.
And there is another factor - how good were the clans at time X compared to time Y? If the clans were weaker at time Y than they were at time X, then a higher rating over them might not be as meaningful as a slightly lower rating at time X.
Anyway, I will consider providing it just for fun, at least. But if it is proven to be meaningless due to the number of clans at time X factor, then I probably don't want to provide it.

I can assure you that the EMP vs NEM war of June 2011 is in there, however because those two clans also had a war back in December 2009, the games,win/loss and % are likely being lumped into one large calculation. I am not the expert, FD is, but I thought I could offer a possible explanation. I do know however that 100% that war IS being calculated.
It is there, just the basis points for each clans rating haven't been updated so you can't see how it counts.
It's the reason why they jumped from 1255 in 6th to 1279 in 4th and why we went from 1124 to 1100...
If a clan plays another clan several times, each war is considered a separate event.
I will update the ratings basis shortly so you will see the impact of each war on your ratings.

(I'm actually surprised our 'loss' to thota didn't net us more points, since I think that was one of our best performances compared to a win over DB...)
It is possible for a loss to give a clan a higher rating than a win.
The settings of Min delta per win/loss and Max delta per win/loss affect this. I have chosen 200 to be the minimum points awarded on top of an opponent's rating to a clan that beats their opponent. I chose 600 for maximum. So the actual value added/subtracted is between 200 and 600 and is linearly correlated to margin of victory.
So even if that NEM barely lost to THOTA, NEM's basis point for the match is THOTA's rating at that time minus 200.
If I used a min value of 0, then NEM would get a basis point near equal to THOTA's rating as THOTA's margin of victory was small.
But I found that using the value of 0 resulted in lower accuracy than using the values I am using.
