Q Hyun-dance traditional mode evaluation scale

I have finished the one-step score calculation formula of QQ Hyun Dance 2 traditional mode.

The formula mainly consists of three parts:

Number of arrow keys = x

Number of reverse keys = n

One-step judgment = a

Among them, A is influenced by st(showtime) and non-st stages.

Each numeric field:

x∈N*

N∈ and n belongs to N*

A is a partial real number.

[Key] Formula: Let one-step score =S,

Then s =10 {5+[x (x-1)/2} * a (1+0.2n).

Here is the value of a,

Non-st stage: bad = 3 good = 5 great = 7 perfect = 10 perfect+(even P)=5+5*[ even P]

St stage: bad = 16.5 good = 27.5 great = 38.5 perfect = 60 perfect+(even P)=55+5*[ even P]

Application example: In the traditional mode, when someone plays well in the lv8+ 1 anti-critical stage, his/her score for this step is:

10{5+[8(8- 1)/2]}*7( 1+0.2)=2,772
