Does a consolidated award chart exist that lists the # of miles it takes from different airlines for an award ticket to the different zones?

I was going to create one that combines the major players (UA/US/AC/BA/AA/DL) into one nice consolidated chart but will not take the time if it already exists.

For example, US --> Europe may be 100K in FC on one airline but 125K on another. If you have lots of miles with different carriers, then this would be useful information.

Yes, it may be easier to earn miles on one carrier vs another, thus your value/mile may be different, but this is still useful.

Also, all airline zones are not the same, but that issue can be overcome too.
