Face: X/20
This is a simple score out of 20. While facial beauty is not the most important factor in judging a pornstar, it is certainly more prominent in judging than the bodily factors, since all body types are susceptible to this category.
Tits: X/10
This is a score out of 10. Tit size, while impressive, and important to a pornstar, is not universally necessary for a pornstar to be great. There are a lot of great pornstars with petite perky tits. So this category has to have reduced importance overall to give a fair chance to pornstars of all body types.
Ass: X/10
This is a score out of 10. I am a huge fan of a great booty, but there a lot pornstars who aren't packing nice asses, but make up for it in other ways, or pick positions more suitable for them. I have pornstars in my personal top 10 who aren't packing enough booty to look good in cowgirl, but are still good pornstars to me. So this category has to have reduced importance overall to give a fair chance to pornstars of all body types.
Skill: X/30
This is a score out of 30, created by calculating the score out of 15 and multiplying by 2. Motion of the ocean means everything. I'm judging pornstars, and this is the literal measurement of their ability to do their job. Sexual ability shows dedication, practice, and talent in a pornstar, and it's the thing they have the most ability to control and improve. It is clearly extremely important, and is the first power category in this rubric, worth up to 30 points.
Attitude: X/30
This is a score out of 30, created by calculating the score out of 15 and multiplying by 2. Attitude is the single most important factor for a pornstar. The best pornstars in the world have a variety of body types and looks, but typically have one overarching similarity, they garner popularity because of their attitude. In a porn performance, and in sex generally attitude makes all the difference, so it is the second of the power categories in this rubric, worth up to 30 points.
Final Score: X/100
The point totals in all these categories combined adds up to 100. A 100 is a perfect score in all categories, but no woman is perfect. But let's see who gets the closest.
