Quick WOT PE Tuning Question

Quick WOT PE Tuning Question
Wondering how everyone else separates their data to tune WOT PE? This is what I did:
1. Drive and Log
2. Export to Excel
3. Since PE mode enables above 26% TPS for any above 4400 RPM I deleted all data below 4400 RPM.
4. Delete all subsequent data below 26% TPS
5. Plot data on graph (Wideband AFR vs. Time)
6. Adjust accordingly
I just followed this sequence and I am at step 6. My graph is all between 14-14.75 AFT for this data. What is a good starting amount to decrease from my PE vs. RPM table to get closer to 13.1?
Anyone have a better way to tune PE WOT???
Thanks

Maybe asked a million times, but what is the ideal A/F ratio for P/E on a naturally aspirated engine?
Also, should I disable P/E to work on VE tables, or just tweak P/E for anything above 4400?

I read somewhere that you should tune EVERYTHING to 13.1. Any input on this?
Oh, Im using HPtuners and an LC-1.
