Default Question on OLSD tune w/ wideband

I've read through a few different tuning articles/guides and I think I have a grasp on what I need to do but want to make sure before I go waste some miles of logging. In OLSD w/ my wideband connected in one of my collectors I just need to drive around (say 50 miles max) to log as many different cells as possible and log AFR error which is ((commanded-actual)/commanded)x100% and then take the results and multiply them into my VE tables. Do I do the full correction or should I take say 50% of the correction and then do more logging and do another 50% and keep going until there is no more error.
TIA

I do the first 2 logs at 100%
then from there out I do it at 50% or paste special-half depending on what datalogger
as it gets real real close..I do a -half....then I average the old and new..
I'm down to where I have it within .3% on everything..LOL


I usually get plenty of data in 15-20 minutes of driving....
