I don't know, it does sound like she has doubt in her equipment and she should, that's a good healthy attitude for any diver to have. I have dealt with mechanical systems all my life that mine or someone elses life depends on. And no matter how new, advanced or well maintained a mechanical system is there should always be backup system, and plans or systems, to deal with catastrophic unexpected system failure. I'm sure if she makes a list, mental or written, of all the possible failures or emergencys she envisions could happen (I have) And she has a plan or action, or "out" to deal with those contingents she will have no problem diving within her new "safety zone"
About 30 yrs ago when I was getting into motorcycle racing I was watching videos of an American world champion motorcycle racer(Kenny Roberts), he made amazing saves, getting back in control of the seemingly uncontrollable. Even when he'd throw the bike away he seemed to know how to land or slide with doing the least amount of damage to himself. In an interview after 1 race where he came from behind and made several remarkable saves while riding over the capabilities of his equipment the commemtator asked him how he new what to do in situations like that with split second decisions and his life possibly on the line. He described how he did it as having "mental packets" prepared ahead of time for all possible contingents so when something happens he tears open the proper mental packet and immediately knows how to react to a given situation. I thought that was the most amazing thing I'd ever heard, what a great concept. I use that system regularly
