Upside is there's fuel available for that tip-in, downside is I get some occasional backfires when transitioning from engine braking back to neutral throttle at low RPMs and low throttle input (e.g. engine braking gently down to a stoplight and popping into neutral just as it's reaching the point where the engine would naturally start to lug out for being too low. If I don't time it just right, nice little fireball pops down the exhaust).

Are you saying you corrected your lean spots in that same A:F table, or elsewhere?
If you do like I did you won't have to backfire, I just drive and watch the correction factor and during live tuning while holding the pedal there while you feel it sputter add the fuel on the fuel comp table but don't go passed 100% leave it a little and I mean a little on the rich side maybe 95-97% and I don't backfire on decel from 7000k down to 800 idle.
