You're right, maybe "simple" wasn't the right adjective. I agree with your insistence that it involves more than setting a price on a single tier. It seems it didn't come through in my last post, but in an effort to be brief, I didn't elaborate on how that not-so-simple calculation would necessarily involve a reevaluation of the entire line underneath the custom tier, as the mapping between previous top tier skate sales and new custom skate sales wouldn't be 1:1. That's why I was envisioning the calculation would have a volume range estimate, hinting at the indirect translation between current and imagined skate lineup schemes.
