As per current scenario, if a blog gets 6 ratings it gets a star, 12 ratings gets two stars and 18 or more rating gets three stars. Can we change this star system to five star?

Requirment for five star should be 30 or more ratings. If a blog gets 24 ratings it should get four stars. It's my proposal to get five star rating system.

Current rating system
0-5: zero stars
6-11: one star
12-17: two stars
18 or more: three stars.

My proposed rating system
0-5: zero stars (no change)
6-11: one star (no change)
12-17: two stars (no change)
18-23: three stars
24-29: four stars
30 or more: five stars

My request to Moderator sir to please implement this five star rating system.
