Hyperaccelerator Disk not working as intended?

Ok, well I've never equipped that disk, so don't know if it's ever worked.

I always thought speedng these enemies up wasn't going to help, and you can get almost the equivalent effect from a 1 dot caustic emissions disk, but no speed up involved, or even having to hit them. After they've taken 2 turns they could have 4 dots and burning on them which is about 10% max health damage too.

That disk is a terrible use of your capacity.
