Default Timing Method has been changed to 'Time with Load' since we don't have a load remover for console version.
I'm not so sure this is a great idea in the long run, PC load times are weird and get longer over time the more missions and different weapons you use and having to use RTA instead will encourage stupid strats like quitting and restarting the game mid run because the time loss from loads getting longer over time is higher than the time loss from just restarting the game to reset them or having to take into consideration that reusing the same loadouts reduces load times degradation. Not to mention one of the recent windows 10 update had the side effect of making the PC loads 5-20 times longer for some people.
There's also the question of people who have an SSD in their PS4, though that's easier to deal with.
Not that I don't understand the reasoning behind the change as manually removing loads is too work to reasonably be done especially for full game runs and separating platforms would be fragmenting a very small leaderboard with little activity.
