Remember that these are supposed to be the kinds of early adopters with the most to gain from the program. Put another way, what if all ten early adopters decline to volunteer again? That would be a highly significant—and very negative—result. If the numbers from such early experiments don’t look promising, there is clearly a problem with the strategy. That doesn’t mean it’s time to give up; on the contrary, it means it’s time to get some immediate qualitative feedback about how to improve the program.
