I originally got a bit confused by the chart as well, but no it's not an error. I think the distorted pie chart is meant to show Hanano's false confidence in the results. (maybe she's too blinded by all those stars in her eyes)
Fixed an error in the translation: In the panel where Hanano and Lotte are entering the Hunters guild, I replaced the description "Up Ahead" with "Some time later".
Fixed an error in the translation: In the panel where Hanano is holding up her hunter license, I replaced "O Heavens!" with "I'm a genius!"
(I'm really bad at reading hand-writing sometimes)
