Time Attack IGT/100% clarification paste

Time Attack for 100% must be totaled up for all the engine classes you completed them with during the run in the (in game time) area along with submission you can also highlight this portion or portions of the 100% run and submit it to all Time attacks (the engine classes category(s) 4,3,2,1) respectfully. so let's say all time attacks totaled to xx:xx:xx.xxx (x being any number) for all the classes can be submitted there as well you can either highlight those parts single or include the full run for those submissions as long as you use the "copy URL at current time" function so it's easier for me to verify quickly
