Potential系统于v1.1加入，是衡量玩家水平的标准之一，同时也是Potential解歌系统等机制的基础。
Potential组成
Potential（可简称“ptt”）由40个成绩取均值而成，其中30个best成绩（简称“best30”或“b30”）和30个recent成绩（简称“recent30”或“r30”）中的10个top成绩（简称“recent top10”或“r10”）。
- best30是所有谱面中最高的30个成绩，中间没有相同的谱面出现（可以是同一首歌的不同难度），该部分的值只升不降。
- recent30是较近30次的曲目游玩成绩，按照时间顺序排列，其中取10次不同谱面的最高的成绩作为top
- 上传一次成绩后，更迭分两种情况：
- 分数小于EX直接写入末尾，recent最早的成绩写出，也就是按时间顺序写入与写出recent
- 分数大于等于EX或者困难模式Track Lost，如果比top中的最小值大（也就是可以更新top），那么会把recent中ptt最低的pc写出（同ptt则取最早）；否则不计入。
- 虽然v3.0.0以后Recent的成绩计算时去除了相同谱面成绩的影响，但是在一定次数游玩后依然会写出最早的Recent记录，即使你在此期间仅仅游玩过已经写入Recent的谱面
- v3.0.0之后任何Recent成绩不论分数，在写入时都会保证Recent30内仍有至少10个不同谱面的成绩（如果之前的谱面种类不足10种，则保持种类数不降低）。
- 这里的困难模式Track Lost就是指Hard回忆条降至0导致的Track Lost，与EX效果相同
- 光（Fracture）的Overflow特性虽然会触发Hard模式回忆条，但是结算并不归于Hard而是Easy
- 对应的，由光（Zero）触发进入Fracture Ray时，或由对立触发进入Grievous Lady时，为真实Hard模式。
- 上传一次成绩后，更迭分两种情况：
- Potential为通过联网计算再获取返回值，在多设备登陆的情况下会出现多次上传成绩，因此有的截图并不符合上述规则
单次成绩ptt计算
| 分数 | 单次成绩ptt |
|---|---|
| ≥ 10,000,000（即PM） | 定数+2 (此时屏蔽物量影响) |
| ≥ 9,800,000 且 < 10,000,000 | 定数+1+(分数 - 9,800,000)/200,000 |
| < 9,800,000 | 定数+(分数 - 9,500,000)/300,000 (下限为0) |
所以说，单次成绩ptt为0的通式为
分数 ≤ 9,500,000 - 定数 × 300,000
总的来说，单次成绩ptt与分数的关系见下
| 分数 | 单次成绩ptt |
|---|---|
| 10,001,450 | 定数+2.00 |
| 10,000,000 | 定数+2.00 |
| 9,950,000 | 定数+1.75 |
| 9,900,000 | 定数+1.50 |
| 9,800,000 | 定数+1.00 |
| 9,500,000 | 定数 |
| 9,200,000 | 定数-1.00 |
| 8,900,000 | 定数-2.00 |
| 8,600,000 | 定数-3.00 |

| ≥ 9,950,000 且 < 10,000,000 | 定数+1.5+(分数 - 9,950,000)/100,000 |
| ≥ 9,800,000 且 < 9,950,000 | 定数+1+(分数 - 9,800,000)/400,000 |
| < 9,800,000 | 定数+(分数 - 9,500,000)/300,000 (下限为0) |

测定方法
- 本部分参考资料来源于Fandom WIKI
| 历史回溯法(choka法) |
|---|
| 由于3.0版本的recent成绩不再包含相同曲目，因此这个测定方法已经失效。
原理：30best+10recent，AA时单曲成绩ptt等于定数
|
| STEP法(robert法) |
|---|
| 原理：World模式的STEP值与单次成绩ptt成绩有关
如果在World结算时，初始的STEP值大于2.5 定数=(9,500,000 - (分数 - ((初始STEP值-2.5) / 0.004473062)^2)) / 300,000
STEP最小值= max(加成后STEP值 / (人物STEP数值/50), 初始STEP值) STEP最大值= min((加成后STEP值+0.1) / (人物STEP数值/50), 初始STEP值 + 0.1)
STEP最小值= max(加成后STEP值 / ((人物STEP数值/50)×play+加成), 初始STEP值) STEP最大值= min((加成后STEP值+0.1) / ((人物STEP数值/50)×play+加成), 初始STEP值 + 0.1)
缺点：受World体力限制，定数越低要求分数越高，需要大量时间金钱投入，精度不够（最高±0.2） |
| 数据回溯法(Xecus法) |
|---|
| 原理：使用了lowiro的api，返回的是精确数据
通过访问api来获得最近分数以及对应ptt，由公式反推获得定数 优点：一次算出，精度最高 缺点：1.8.1后只能查到最近游玩成绩对应ptt |
研究过程与验证
- 根据JPwiki Arcaea的FANDOM wiki中Potential页面的算法，ptt由best30和recent30中的top10构成
- v3.0.0之前的EX保护机制
- 在现有ptt计算准则条件下，有关recent的记录常常有一定出入，在某一单曲得分对应ptt低于现有总ptt平均分时，有些情况显示keep而有些情况会产生扣分，由此推测对于recent的记录是有选择性的。
- 根据robert_cpp的计算表附加说明，“持续得到EX评价时无关曲目的其余任何条件，ptt会始终保持keep结算。”
- 有理由认为recent的记录出入与是否得到EX评级有关。
| Vanitas的掉分实证推论过程 |
|---|
| 先放置清空recent（结算根据是：当前ptt=30个best总成绩之和/40，说明recent总和为0。）
24次FTR EX(无PM)外加高定数曲目5次AA和1次标记项目，且计入ptt计算的10次recent得分(含AA项)偏差值在±0.4以内， 再持续获得30次PST/PRS的EX+FR时，ptt始终保持keep，下一步即第31次完成标记项目(SOUNDWiTCH FTR半放置等效得分8.4，小于上一步最后成绩得分Sheriruth PRS(9.7)) 同时成绩严格小于前30pc任意一次； 此操作过后立即开始30次放置掉分，结果显示在前20次放置中ptt整体减分有0.05，主要减分阶段在最后10次； 结果以及分析结论 标记项目得分8.4的成绩在最后被去除(-0.21)， 9.8 说明10项最高recent记录并不会被最后整理至写出队列尾部，而是依旧保持日期顺序。(否则前20次不会掉分) 最后10次任一减分对应单曲成绩(-0.27±0.01)均大于上一步所达成的全部次难度成绩 由此可知PST/PRS EX的任何记录没有写入到recent。 推论是：对于任何EX评级的成绩，如果将其写入recent队列会导致ptt下降，则该成绩并不会写入队列，而是直接舍弃，故将其称为“EX成绩写入保护”。 【并不是一度认为的EX recent成绩一定会被保留的观点】 此机制的存在可以充分解释为何h1r、higllus等人为何在最后集体刷全难度理论值时并不会因为recent记录一些交替而导致掉分，因为在EX后的记录如果成绩太低并不会写入recent。 至于掉分的情况的论证则很简单，五月初爬梯子只打Blaster连续15次不足EX就突然被扣了0.02，五月二十日conflict推分掉ptt截图在推特可见 对于爬分玩家而言，此机制的存在相对避免了了断网保分的极端措施，EX之上即可获得保险 |
- PM保护机制证伪说明(2018.06.29)：由RichadoWonasas的掉分个人证明，其ptt在recent为0的情况下为8.80，等效为11.73平均分。
- 掉分前已PM过Cybernecia Catharsis，当时定数为9.8，PM得分11.8>11.73。
- 很明显若PM具有强制保留机制的话那么其放置30次的结果应大于recent为0即8.80的情况，故PM强制留存记录的机制不存在。
- Blurring Shadow发现了Xecus的机器人可以查询单次游玩的ptt后，联系了页面编辑者Vanitas和RichadoWonasas进行相关实验，修正了单曲ptt计算系数
- 一些定数勘误有【FTR】Fracture Ray 11.2→11.1 The Message 9.8→9.7 Sulfur 9.9→9.8 【PRS】Grievous Lady 9.2→9.1等（均为v3.0.0之前的定数）
- 关于v3.0.0之前9,800,000 - 9,949,999分数段内的变化率比例（即，这一段分数内PTT增长率与9,800,000分以下的PTT增长率的比值）为0.75的证明可参照RichadoWonasas的专栏PTT研究附录：一个被误算了许久的比例。
