I know I'm comparing a wipe to a clear, but...

I'm honestly really confused by this. Hak's dots are an average of ~100 higher than mine throughout the entire duration of this parse. We have similar buff usage and everything, yet no matter where I look, Hak's beating me by this same margin in the dot ticks. I'm sure I'm failing to optimize elsewhere, but this is kind of silly? My own testing is showing numbers in line with what my parse shows. Is ACT really this bad at reading dots? Do Hak's dots really do that much more than mine? I'll accept whatever answer, I just am really confused by this.
