Hey Chris, Thanks for the explanation, Please ignore the 250usecs that was my mistake, just think of it as 20usecs. Just clarifying the last thing, so basically every status change require that extra usec just like the one did in my example at 16th usec and 37th usec which you fixed. So wouldnt it be also an extra usec for the status change from ready to running at 48th usec? and the transition time should from the 49th second. Or does that specific status change not require the extra usec. Please let me know.
