A simple but useful equation found by Hideyoshi Sakamoto aka Piersss, to calculate the number of ratings on your map without having to check it directly.
The Equation:
f = x/y
f = Initial function
x = Total stars on your map
y = Total players who have been rated on your map
Example:
Piersss has a map named Liposome with over 53 stars and 18 players who have been rated on his map. Calculate the total of his map rating
Known:
x = 53 stars
y =18 players how have been rated on his map
Completion:
f = x/y
f = 53/18 = 2.94
In conclusion Piersss's map Liposome has a total of rating at 2.94 point.
