Cooking experience does not scale linearly

Previously, it has been raised in game that the cooking experiences are not linear according to cooking level exp. For instance, food with buff effects (e.g. bluegill sashimi, beast and birdie stew, cooked tiny fish chunk, strawberry treats) have exp/sec that are way higher than the foods produced around their level.

Subsequently, they were adjusted to that they scale linearly. However, with the recent update (5th Jan 2017), the exp for these food items have been readjusted back to the original values, which do not scale accordingly.

Is the latest readjustment of exp values intentional?
