You should change the formula. ESR should be the most important, even if it goes into lower tiers, and it's more penalized. Not a lot of people have too close or too far ESR. But, it's more like 48.2, 43.8, etc.
I also think tfwhr, jaw width, etc should be less than facial thirds since that's balance.
To me, and I got these from other raters:
1: ESR
2: Facial thirds
3: Fwhr
They can be in other orders, but those 3 are the most important.
Since they're the most noticeable.
Also, MFR, it is useless. Use EME, the ideal is: 45-49. MFR is too based on eye spacing (IPD) and the upper lip. Someone can have a shit upper lip, but too far eye spacing and it's gonna come out as ideal. Since EME is taken from middle of the mouth, it takes how compact someone looks.
