Hey, I'm really glad you're enjoying this plugin. I'll be making a small fix to try and isolate this parameter so the chart displays the data directly from the player's data, and not the result of a formula within the plugin.
This way, we'll have the ATK 3 value isolated in the chart like this.
I'll be implementing this change in the next version.
Thank you for observing and reporting this behavior, and thank you for all your support!
