There are a lot of different things we're doing. For example, one thing that we've done recently is we've established a group of senior managers and, on a monthly basis, we talk about every single trainee who has any difficulty.
One area where I think we've improved is that, at times, we would wait until there was a recommendation to cease training in order to take action. Now we get involved a lot earlier, and then we invest in helping the person in training as well as the person conducting the training. The team responsible for the training gets into coaching coaches and extra simulation runs into whatever the person needs earlier in the process.
I don't want to say that we've found the solution for everything, but, as I said, since we've started training again, we have seen a better success rate overall than we saw pre-COVID 2019.
