i'm a relative newbie to unix (i'm on OSX) and i have a specific problem i'm tripped up on:

i'm piping the output of top (in log format) into an awk command which formats the information (and eventually will send it out continuously via udp/osc to another app). my problem is with what comes up in the terminal when i try running top -l1000 | awk -f filterfile. the samples pop up two at a time! i need for them to be at relatively constant intervals for this application. does anyone know why this might be happening? i've included my (simple and kludgy) awk file below. thanks in advance for any help.
