I´ve been triying to get the same time but it is impossible to me. Can someone explain this please?

Look at this tread : https://www.speedrun.com/leagueofevil/thread/r2hvc I hope this will help you to understand :) Else, ask again.

So it´s impossible to start running in the black screen? If that´s true , thanks for the help a lot but if it isn´t can someone explain better please?

When you die/start/restrart a level in this game, the inputs are resets : if you maintain right, you have to hit right again to start running at the start of a level. The developers forgot to apply this to controller, so the first directionnal input doesn't start the timer.
