Repair Box Critical Question

Im still puzzled by how critical works for repair boxes. I currently have my feelix with 15% crit chance and critical repair amount increased by 50%. My base box healing is 364 and a total of 464 with perks. The max heal i see is 480ish. Can someone enlighten me on the calculation of this and how much is my expected critical heal? From what i understand is it should be at least 1/2 of 364 plus the 464 total which would give me at least 600ish. In need of your all-knowing guidance. Thanks

 

Crit heal chance is 5% max. What you have is 50%+ crit hp, not chance. Kind-of like crit dmg perks in cannons.
"Repair Box Launcher critical repair amount increased by 50%" is the wording I believe.

 

I never used box critical, but I believe the base crit should be +100% like with weapons, meaning with 50% extra a critical box would heal 2.5 times the normal amount, being 2.5 times 464.

@The Otherguy box critical isn't 5% max, there are 3 crew trainings with 5% each

Edit: actually I'm not sure about 100% being the base crit bonus, it could be 50% for box

 

Ohh that's a bummer wasted my 4 talents with just 50hp lmao

 

Oh well gotta ditch them talents not working for me. Not working as i've expected.
