Hmm....I haven't really thought of the math behind the durability of the field, but it certainly is no ultimate defense mechanism. 

If I can compare it's defensive capabilities to anything, I'd say it possesses the same level of strength as Violet's shield from the Incredibles 2. So it's quite durable, but certainly has its limits.

But to quantify it's durability before it shatters? I'm not sure. I think it's situational, but using practical reasoning to justify when it shatters and when it doesn't should be good right? Not meta-gaming it as some omni-shield essentially. Stopping a vehicle wouldn't shatter it, but stopping a continuous onslaught of bullets would eventually shatter it. Just depends on the force and how powerful and/or persistent that force is against her.

Hope I clarified it as best as I could. If you have a certain limit you have in mind, I don't mind adhering to it.

Cheers!
