If you reset the ECM it just starts from scratch and takes less time to learn your new habits and driving style.

Yes, pulling fuses #5 and #20 resets the entire ECM. Yes, the ECM does adapt to your driving style. However, once you are in the low fuel table you are stuck there. The only way to get back up to the high fuel table is to do a fuse pull.
