repeating single use execute with cooldown and misc

currently trying to work out a per player finish line detection with a set cooldown delay additionally If someone wants to help me further. With the finish line detection I want to trigger an action that takes the current value of a players scoreboard converts the value from ticks/s to min+sek+ms and compares it to other scoreboards to determine the lowest global value. tried to do the conversion with modulo scoreboard operations to minimize scoreboards but failed miserably. -# Im trying to minimze repeating tick functions, scoreboards and nbt checks as much as possible thanks
