There are other hidden costs to repairs too. One is you’ve “broken the seal” and now your device isn’t “stock” anymore. The water seal might not work as well. The display connector might be slightly loose and tweak out. The screws might not be factory torqued down.
For a car it’s similar too… maybe after that accident the frame is now just slightly off kilter. Maybe there was that proverbial “extra mystery bolt” left over.
Then there is opportunity costs. Is repairing it really the best use of your time and money? What other things could you have done instead of repair? I dunno…
All I’m saying is, repeatability isn’t the end all be all. It’s yet another set of trade offs factored into product design like security, user experience, quality, cost, time to market, size and weight, durability, etc.
I think the score is fine. But there is a second score not mentioned that is “is it worth repairing”?
