its called "closed loop correction %" on tuner pro. not sure why it is called closed loop since you are running open loop during wot. maybe it just doesnt differentiate between the 2. either way, 100% means no correction, and >100 is the % of fuel added for target a/f, and <100 is the % of fuel subtracted for target a/f.
i would suggest not running in emulation mode while tuning w/ a/f tracking. i usually datalog my run, then look back to see the % and make changes in my map. i also dont go quite as far as the shown value. i.e. it says 91% (-9%) i may just change it to -6 or -7 and do another run.
also, there is a newer version of tuner pro available. it was released last month in case you dont have it.
here is the link on my website, 5 files down called "tunerpro v414 newest"
hope that helps
