Honestly I'm all for doing IGT but we would need to test it in depth first (on both 360 and One) as I think it is a better way to time as well (along with this, loading times could be tested as well). I have been thinking of improving my pb/record anyways as I think a sub 2 RTA is easily possible so this is a good way to force me into actually doing runs again. We will have to see what others think as well though.

I haven't done extensive testing towards the accuracy of the IGT but from what I've seen it seems to be accurate. I started doing mine in RTA since that's just what was done before me though I always did wonder about doing the timing using IGT. Currently there are no records in the level leaderboards but as long as we can confirm that the IGT is accurate, I definitely feel like they should be done using the IGT. The argument I can see being for using RTA in full game runs is that it is much faster to just pass through the end of level rather than waiting for the time to show up. On top of that, I'm pretty sure the cutscenes do not contribute towards the IGT so people not skipping them quickly would affect their RTA while not affecting their IGT.
