And over a 3-year period, as I mentioned, the core of the stock, 2B, 2C, 3A, and 3B would have comprehensive coverage. But not— that is not the case over a shorter period of time. So in 2027, the design that we propose, base clock design, features sampling half the charter regions in 2B, 2 or 3 charter regions in 2C, half of the charter regions in 3A, and 205 in 3B, with additional sampling outside of the core of the stock in 2A, 4CD, and 4B. And again, this area in the far west of 4B is the region we tried to sample in 2022 and got no bids on, and we'll see how it goes.
