Relative Speed time
To search for fast opponents what often matters more is not the actual speed time but a relative speed time, compared to the boot time (It is a big difference if you need 8 hours in a 5min boot game or in a 3days boot game) or to the speed time of the other players in the game (e.g. sometimes you talk with your team-mates about a strategy or with enemies about a peace treaty)
This is now possible.
I absolutely agree. I think movement speed should be displayed as a percentage of the direct boot time. So 50% would mean that, on average, you use 50% of the allowed turn time.
