start="$(date +'%s%3N')"

duration=$(($end-$start))
cat  "$par $duration" >> result.dat

echo "$par $duration" >> result.dat

You use cat which will echo the content of the file with the name formed by "$par $duration". This will most likely not exist, so that you end up appending nothing to result.dat.
