See < http://tutoree7.pastebin.com/9Q8u3wLw>. It seems you're correct, in that if I hit 'y' 10 times and then 'q' to close, I'll get "c = 11". 5 'x's and 5 'y's and a 'q' also gets "c = 11", of course. Out of curiosity, I tried holding down 'z' (i.e., neither 'y' nor 'q' for exactly 10 seconds, and then hit 'q'. Got "c = 267". Thanks, Alan.
