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。

由于兵器转盘活动前期经过几次改版后，很久没做调整，目前的性价比逐步走低！
特别是20金的8倍，我们来看看具体情况。
然后，我们可以计算概率数量积数，取得均数。

对于8倍购买的计算！是大家可关注的。
**给的内圈数字1-8，概率均匀分布，则可计算如下：
ignore_js_opimg id="aimg_961837"src="https://res-bbs.aoshitang.com/data/attachment/forum/201501/04/96183715e7591eb8216f5a6c64a28105cdf340.png"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/201501/04/96183715e7591eb8216f5a6c64a28105cdf340.png"file="https://res-bbs.aoshitang.com/data/attachment/forum/201501/04/96183715e7591eb8216f5a6c64a28105cdf340.png"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
由于**内圈数字还可能不均匀分布，则后续性价比更低，在此先假设**不坑，来进行考虑。
然后，我们可以根据该分布测算性价比
ignore_js_opimg id="aimg_1086283"src="https://res-bbs.aoshitang.com/data/attachment/forum/201505/08/10862837a47e471d2b097548e9e576283afb441.png"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/201505/08/10862837a47e471d2b097548e9e576283afb441.png"file="https://res-bbs.aoshitang.com/data/attachment/forum/201505/08/10862837a47e471d2b097548e9e576283afb441.png"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
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。
如果**把金币花费个数进行调整，那回是怎样的情况呢？
如果调整为10金，则：
ignore_js_opimg id="aimg_1257549"src="https://res-bbs.aoshitang.com/data/attachment/forum/201510/10/1257549cc55409440f4d04fc25ade819b08e77b.png"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/201510/10/1257549cc55409440f4d04fc25ade819b08e77b.png"file="https://res-bbs.aoshitang.com/data/attachment/forum/201510/10/1257549cc55409440f4d04fc25ade819b08e77b.png"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
可见，这性价比仍然很低
如果调整为5金，则：
ignore_js_opimg id="aimg_1257551"src="https://res-bbs.aoshitang.com/data/attachment/forum/201510/10/12575515bd6d11ebfe2d236078fbee43f4c0194.png"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/201510/10/12575515bd6d11ebfe2d236078fbee43f4c0194.png"file="https://res-bbs.aoshitang.com/data/attachment/forum/201510/10/12575515bd6d11ebfe2d236078fbee43f4c0194.png"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
可见，这性价比在最后几档马马虎虎可以接受，但非R仍然可以无视。
所以希望**根据目前的实际情况，作出调整哦！
