Sorry to be the bringer of bad news and all, but as some of you might have guessed - this is a bug and will be fixed.
Enjoy that crazy DTE % while it lasts folks :)
Edit: To clarify, we're not saying that it was introduced with TU6 but rather that 50% DTE is not intentional.
We appreciate that a 50% DTE masks in your builds are popular as it gives an edge on difficult content and i'll bring that up in the discussions internally.
