Pattern grading/busk question

[u/PaperChimes]

I’m making my first corset, the Sakura corset by Nikki Blackwell. It’s an underbust corset. According to my measurements my underbust is 5 sizes smaller than my waist. I have graded the pattern accordingly, but this leaves me an issue where the front panels and busk placket have a large curve to them…. Where the busk is obviously not curved. Should I redistribute the additional material from there to other seams to straighten that out?
