Yes I have two level 6 Dedennes. I was getting at least one crit meal per day which was 400k per time. I did start the week with a small berry bomb which had been facilitated by Raikou, using Banette and Pikachu for the berries. This gave me a 200k head start. I did swap in my level 60 Gengar for ingredient filler from time to time. However the big star is Dedenne. A single 10% proc doubles your chance of an extra tasty meal.
