My experience is, yes, we're seeing the cycle shortening.
The shortening of the cycle may well be driven by the technologies, for example, moving from clay models to being able to do digital CAD, sometimes in just hours. Also, from our deeper understanding of global markets and global market opportunities, we're very much more a global enterprise from the industry perspective than we were 50 years ago. That knowledge also drives the competitive cycle. The lag is shrinking. It's really important to understand that the lag between discovering a scientific principle and then understanding how to embody it into a technology is still longer than our ability to take a nascent technology and drive it into the marketplace. That part is getting faster. I think the time between discovery and understanding the technological implications is still longer.
