The good tools will crimp to the proper pressure and make it obvious when it has happened.
Unfortunately the good tools aren't cheap. Even when they are used, some techs will substitute their own ideas of how a crimp should be made when nobody is watching them.
So outside of waiting time, I can go from eplan to "send me precrimped and labeled wires that were cut, crimped, and labeled by machine and automatically tested to spec" because this now exists as a service accessible even to random folks.
It is not even expensive.
Onepull does it.
Precutwire does it
Even dirtypcbs does it
Rittal and others who make the processing machines can point you towards tons of folks
Abdicating responsibility to those "good tools" are why shit never gets crimped right. People just crimp away without a care in the world. Don't get me wrong, they're great for speed and when all you're doing it working on brand new stuff that fits perfect. But when you're working on something sketchy you really want the feedback of the older styles of tool that have more direct feedback. They have a place, but you have to know what that place is.
