因为现在法师的五转技能不稳定记忆可以固定为终极无限，故有了两个终极无限技能，4转终极无限冷却时间固定为180s，而五转不稳定记忆冷却时间不固定68-272s不等，既然要保持100%不断终极，那么我们就取最大时间272s冷却计算，即五转不稳定记忆与四转终极冷却平均值为226s，那么要维持不断终极无限持续时间只需要113s就够了（因为可以放两个），而持续时间＝40×(1+增益时间)，反推出增益只用堆到182.5%，我这么算对吗，求大佬们指正

Saw a redditor made a spreadsheet and post on the different levels of UM and how it impacts the percentage of infinity uptime, i decided to make one the buff duration required to achieve 100% infinity uptime with unreliable memory.
Please note of the following: -
Unreliable memory CD at maxed level is 340s, and 323s with Mercedes Legion (5%CDR)
Buff duration achievable in-game differs from different server/event.
With Decent Combat Orders, Infinity buff lasts for 41s, and mage 4th job buff duration is at 55% instead of 50%
Unreliable Memory CD is used for the average calculation because it is the longer cooldown as compared to Infinity's CD (323s vs 171s)
It is possible to use THREE back to back infinity as long as you have ~110% buff duration
As the lowest UM CDR (20%) has only 1% probability, it is more practical to look at the 2nd row instead as it still makes up 99% of the probability.

不用这么麻烦，堆到200%肯定够用

不带增益怪怪的情况下能堆到175
如果机械师250级可以到180

反正我目前183%，有时候会断十几秒

实际上200%+才稳定一些，180有时候来个4分钟cd不稳定记忆就接不上，刷原初怪的时候很难受

别管断不断，没有保buff就是白瞎
