No. With same set of files, i am getting it correctly. Were the source files created in unix or windows ? You may want to do 'dos2unix' on the input files to ensure it doesnt have any ^M


Code:
$ awk '(FNR>1 && NR==FNR){a[$2]+=$4;s=FNR;next;} (FNR>1 && NR==s+FNR){a[$2]+=$4;next;} FNR>1 {a[$2]+=$4; print $2"\t"a[$2]/3}' f1 f2 f3

4408440    124.333

for just the result and no other fields, use only "print a[$2]/3" at the end.

NAME
ascii - the ASCII character set encoded in octal, decimal, and hexadecimal DESCRIPTION
ASCII is the American Standard Code for Information Interchange. It is a 7-bit code. Many 8-bit codes (such as ISO 8859-1, the Linux default character set) contain ASCII as their lower half. The international counterpart of ASCII is known as ISO 646. The following table contains the 128 ASCII characters. C program 'X' escapes are noted.

History An ascii manual page appeared in Version 7 of AT&T UNIX. On older terminals, the underscore code is displayed as a left arrow, called backarrow, the caret is displayed as an up-arrow and the ver- tical bar has a hole in the middle. Uppercase and lowercase characters differ by just one bit and the ASCII character 2 differs from the double quote by just one bit, too. That made it much easier to encode characters mechanically or with a non-microcontroller-based electronic keyboard and that pairing was found on old teletypes. The ASCII standard was published by the United States of America Standards Institute (USASI) in 1968. SEE ALSO
