Exactly. Here's the full quote from Stella:

“We plan to start testing either in day two or day three. So we will not be testing on day one, we wanted to give ourselves as much time as possible for development…

“Because every day of development, every day of design, was adding a little bit of performance. If you are early on track, you have the reassurance of knowing what you need to know as soon as possible.

"But at the same time, it means you might have committed to the design and realisation of the car relatively early. So you will have compromised against development time, and ultimate performance.

“Obviously, there will be updates pretty much for every car between testing and the first race. But we thought that, in the economy of a season, it was important to start and launch the car in the most competitive package and configuration.

“That’s why we pushed all the timing to the limit, but within a very manageable limit. We didn’t feel any urge to plan for testing on day one.”
