I did not know there were different tournament speeds, But that would make sense. Is there anyway to know what Tournament speed you are on?
The faster "tournament" speed is Legend speed. So, in a MP game with a Legend involved, it will be the faster one.
As (or with) a Master and Tour Master, in ranked and MP rounds without Legends, there will be the slower "tournament" speed.
WGT also chooses between them for some tournaments, even for lower tiers. In this case it's trial and error. Period.
