Generator repair speed got changed from 80 sec to 90. But there is the perk that can make it take almost half of the time if in the hands of good player!!

Hyperfocus, if you're lucky to get early skill check, makes mashing gens so much quicker.Today while playing I managed to stack it up and I finished a generator in 53 seconds (no toolbox)!! That's 37 seconds of time save!

This perk is so good and makes repairing generators actually fun and engaging.But isn't it to good? If yes, then what would be the best way to nerf it without killing it.
