Yes. I think, first, I'd like to correct you, if I may. It's not that we're not going after the -- in the higher power, because we are. We are on track to do the 125 watts, which is 70 wafers per hour and the 250 watts. That has not changed. The only issue is that short term, we are more focused on the stability of the machine, given the fact that we have the delay experience. And it was just as frustrating for us as it is for you. And that, we need to recoup over the next couple of months, and we will. So it is not that we're not going after the high power, it is just simply that the focus today is on the integration and on the stability of that source. Now metrics that you should be looking for, like I started off, we have to have this singular focus on the wattage, which we created, to be honest. And I think there is much more than just wattage, because there is the feature size, there is the cleanliness, there is the contamination control, there is the metrology control, there's the close loop. There's a lot of issues that are surrounding the EUV source, which all make this an integrated source, yes, which also translate back to customers, which is not only wafers per hour, but it's imaging feature size, it's imaging quality, it is overlay requirement. It is all these things that all add to the EUV solution, yes. Now I can make a glitz where all these things I just mentioned are in, and it will make it highly complex for you. The message that I'm giving you is, effectively, we've been pitching you on wattage like this was the only thing, which isn't, yes. So don't use wattage as a metric going forward. We'll do wafers per hour. In the end, that is what customers want, yes. This is what drives the economics of EUV, and this is what we should focus on. And we have made it probably unduly complex by focusing on wattage, which is not the only thing. And I hope that -- if I can give you some help, that I would say the only metric that really counts is the wafers per hour with the stability tool that gives, at least, an availability of a certain percentage for our customers to introduce into the preproduction of their next nodes. And I would start with the wafers per hour, and we will inform you about wafers per hour when we reach those levels and is basically the roadmap. So let's keep the roadmap as the metric.
