awk parses the file only once. One line at a time. Of course that goes for
every invocation of awk... ;)

finaltpi=`awk -v pat="$x" '/TPI chosen/{if (NR==pat+1) print $5' < $x`

tpiert=`awk -v pat="$i" 'tolower($0)~/(average)/{ if(NR==pat) print $5","$10}'
< $1`
If you want more help with this I would suggest that you posted a short sample
input file and a sample of the output you want to achieve. It does make it a
heck of a lot easier to grasp what it is you want to do...
