Second Socks Done

This pair of socks seemed to fly off my needles. Only about three weeks instead of months. Does stitch count and ease of knitting the pattern account for the speed of this pair? These are somewhat smaller and closer to the pattern size.
Possibly it stems from learning so much about turning the heel and gusset that made these go so quickly.
I don't know what, really. I just know I got them done really fast -for me.
Yay!
