For example on World 1 the run is about 7 min and this is probably from all Races of world 1 but the problem is the run must be 9 min like the lenght of the video. World 1 is all Race with the non racing thing if you understand what i mean

It uses in-game time, so the times taken for each track added together, and not real time.

But it wrong

The individual track times were 1:22.81, 1:22.79, 1:20.82, 1:02.70, and 2:17.60, which, when added together, do, in fact, equal 7:26.72.

The disparity between the in-game time and real time comes from the fact that the in-game time only includes time actually in races, and doesn't count time between races in the menu.

Individual tracks yes but not for entire world it is like in MK Wii or Ds on non tracks it counts as well in the time

I'm confused as to what you're trying to say. The "All Races" category is the sum of the individual race times, the "All Levels" category is the sum of all the race times and the non-race times as well.
