如下

有没有大佬会算类似流火之刃这种装备特效在一定时间内固定出手频率时，特效持续的秒数，希望有数学推导过程

这是我python模拟的代码：

import math

import random

import numpy

def getAvg():

p = 0.3 # p*10

v = 3.5 # time*2

add = 8

total = 0

now = 0

for i in range(0, 360):

if now > 0:

total += 1

if now > 0:

now = now - 1

if i % 7 == 0:

x = random.randint(1, 10)

if x <= 3:

now = 16

return total / 2

# print(getAvg())

a = []

s = 0.0

for i in range(1, 1000):

a.append(getAvg())

na = numpy.array(a)

mean = na.mean() # 均值

var = na.var() # 方差

std = na.std() # 标准差

print(mean)

print(var)

print(std)

（

mean：98.85385385385385

var：307.2223850477104

std：17.527760411635892
