兵器转盘活动,已经成为了**带给各位玩家的常见的活动之一。
由于兵器转盘活动频率高,但20金啥时候花,还是有些讲究的。
最*一次改版,**修改了兵器转盘活动方式,最多外圈有15个了,貌似不少!但是否值得花金20获取8倍呢?
首先,如果**给的内圈概率均匀分布,则:

然后,我们可以根据该分布测算性价比

真是不算不知道,一算吓一跳。
这就是说,不管什么情况,用完三次免费拉倒,怎么买怎么亏了。
其次,如果认为**内圈分布不均匀,估算如下:
ignore_js_opimg id="aimg_961841"src="https://res-bbs.aoshitang.com/data/attachment/forum/201501/04/961841974f51e1f6180dff947e7bf066b1cc9e.png"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/201501/04/961841974f51e1f6180dff947e7bf066b1cc9e.png"file="https://res-bbs.aoshitang.com/data/attachment/forum/201501/04/961841974f51e1f6180dff947e7bf066b1cc9e.png"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
然后,我们可以同样测算分布:
ignore_js_opimg id="aimg_1086317"src="https://res-bbs.aoshitang.com/data/attachment/forum/201505/08/10863173ed51ff549a3ff36b6eb3dd8f0522fdd.png"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/201505/08/10863173ed51ff549a3ff36b6eb3dd8f0522fdd.png"file="https://res-bbs.aoshitang.com/data/attachment/forum/201505/08/10863173ed51ff549a3ff36b6eb3dd8f0522fdd.png"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
最终,可形成如下结论:
1、对于非R,无论**的内圈是否均匀分布,最多能达到1:2900的性价比,故任何时候都不应购买20金币。
2、对于中小R,最多买个14,15,当然,也强烈建议免费用光拉倒。
3、大R无视此贴,爱怎么买就怎么买吧。点券,肯定一直都缺,5紫帽子也还得看坚韧度啊!!!
