Purely On Topic  (please keep it that way  guys)
I think the current list can stay, but not as a top-10 managers-list. 
I could accept it as a Top-10 managers of all times list. 
Besides that, I would love to see a new list where current top-managers get the recognition they deserve. 
The ELO-system sounds interesting. 
I would rate League-games and SP-Cup-games at 100%, Friendly Cup-games at 20%, and normal friendly games at 10%. 
I use friendly games just for keeping morale up. I don't care about the level of opponent or winning at all (not even for TS). I usually choose opponents based on country or team-name   
 
 
Friendly Cup-games shouldn't be rated to high either, for it's easy to find a cheap cup with only bad opponents. Good teams could go and play for ELO-points instead of money, and even in cheap or free cups the H-teams can't get to the semi-finals anymore... 
That would be sad. 
The question is, can the ELO-system see a difference between A-teams and F-teams? 
I thought every team starts with a certain amount of points, right? Like 1000. Then, based on the opponent you beat, it grows, etcetera. 
Maybe you can start by giving H-teams 800 points, G-teams 900, F-teams 1000, up to 2000 for A-teams??
Wouldn't that make sense Sjarel?
Also, if you do it that way, you don't have to make a difference in the formula between teams from different divisions. It would pretty much solve itself.
