:I agree that a lot of it is basically WP:OR and WP:SYNTH. The fact that it is "original" calculation (as noted above) is enough to make it unsuitable. Verifiability and no original research are 2 of 3 core content policies. Attached sources do not contain math used in the article. Also, just because it is math does not mean it gets less scrutiny than any other content. And the WP:BURDEN of proof is with the editor adding and restoring the content.  —    ▎
