On my wishlist all my books say Estimate N/A, even though on one book I'm first in line and three wishes were granted last week. Anyone know why?

I don't think they have enough or maybe "long enough" (time wise) history or statistics to be able to tell anything.   At the most it's a guess on their part.  I don't pay much attention to it.

When they first changed the wishlist to include that information, there was a pop-up that said something to the effect of "Not enough Data" to calculate.
