What do I do after JB4 1-7 resets adaptations

Just got my spark plugs changed yesterday.

However, today I got a 2AAF code right after a slightly long crank start up in cold weather (usually instant start-up). Drove back to my home and felt the car idling rough.

Then I did the adaptations reset in JB4.
Scared the hell out of me at first, you know... the extremely horrible engine surge. Anyway, I got it fixed by that holding down the gas pedal.

The engine runs smooth after.

My question is do I need to switch back to Map 0 and let the car runs a few hundred miles just to let it adapt a little or can I jump right back to Map 5 like I had before and drive WOT?
