Whether it’s efficient to use a camp at D3 depends a lot on location, and on whether you really need to get that 4th level information. It’s complicated. If you’re happy to settle for level 3 and recruit based on that, and especially if you’re in the West, using camps - both the private and the local public camp - is a good way to get a lot of players to level 3, and a fair bit to level 4. To get the highest number to level 4, using camps often doesn’t work well (especially in the crowded east), because you can’t control the states you’re drawing from, so it’s harder to use the FSS and assistant in tandem.
