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.
