Only if those simulations are done, for example, by our defence and research and development community. By that, I mean professional scientists and those with Ph.D.s, who have no interest, frankly, in whether product A or product B is better or worse. But we are asking very specific questions about technology and capabilities in very scientific terms. They're not pilots, they're not industrialists. I find them to be very objective, but you have to be careful who you're asking, and you do need to get the companies and the commercial interests set aside from that question.
For example, on armoured vehicles, we insist that we have an independent third party attest to the survivability results, who is not paid by that company or in part of that country. That's what we feel is the measure of independence that's required.
