I'm not very familiar with the script, but does this fix it?

This can be further simplified using a single awk command to: a) skip all header line (assuming they start by #) b) printing the third column of all the following pair numbered lines
which is something like:
LOGFILE=rt-app_$1_run$3us_sleep$4us.log for i in $(awk '/^#/{HC++; next;} {SN=NR-HC+1; if(SN%2){print $3}}' $LOGFILE)
where I've used: HC (HeaderCount) : counter of header line SN (SampleNumber) : counter of samples lines NR (Line Number) : awk's predefined line number variable
