Yes I think "wxCover" the author chose 10 because the small aes1610 would
get you fewer minutae to work with than other devices.
See this quote from him nearly 2 years ago Nov 19, 2007, if you search the
list archives you can find the early discussions around that time:

"Well, I've spoke too soon in my last mail! I hadn't tried to enroll and
verify. The images I get looks nice BUT for the moment, I have problems
with enrollment and verification.
I think the main problem is that I'm not getting enough minutiae.
Usually, for a fingerprint that looks really nice, I get something like
10~15 minutiae. And if the image is not perfect (very often), the number
is less than 10.
Now, speaking about verification, I haven't manage to get it to match.
The scores are always low. I think this is due to the poor number of
minutiae.
I don't know how to improve the situation. Is there some tweaking we can
do with the algorithm which calculate minutiaes ?
I'll try to see if I can make it work better with my code."
