潛力值
Potential系統於v1.1加入，是衡量玩家水平的標準之一，同時也是Potential解歌系統等機制的基礎。
Potential組成
Potential（可簡稱「ptt」）由40個成績取均值而成，其中30個best成績（簡稱「best30」或「b30」）和30個recent成績（簡稱「recent30」或「r30」）中的10個top成績（簡稱「recent top10」或「r10」）。
- best30是所有譜面中最高的30個成績，中間沒有相同的譜面出現（可以是同一首歌的不同難度），該部分的值只升不降。
- recent30是較近30次的曲目遊玩成績，按照時間順序排列，其中取10次不同譜面的最高的成績作為top
- 上傳一次成績後，更迭分兩種情況：
- 分數小於EX直接寫入末尾，recent最早的成績寫出，也就是按時間順序寫入與寫出recent
- 分數大於等於EX或者困難模式Track Lost，如果比top中的最小值大（也就是可以更新top），那麼會把recent中ptt最低的pc寫出（同ptt則取最早）；否則不計入。
- 雖然v3.0.0以後Recent的成績計算時去除了相同譜面成績的影響，但是在一定次數遊玩後依然會寫出最早的Recent記錄，即使你在此期間僅僅遊玩過已經寫入Recent的譜面
- v3.0.0之後任何Recent成績不論分數，在寫入時都會保證Recent30內仍有至少10個不同譜面的成績（如果之前的不同譜面數量小於10，則保持不同譜面數量不降低）。
- 這裏的困難模式Track Lost就是指Hard回憶條降至0導致的Track Lost，與EX效果相同
- 光（Fracture）的Overflow特性雖然會觸發Hard模式回憶條，但是結算並不歸於Hard而是Easy
- 對應的，由光（Zero）觸發進入Fracture Ray時，或由對立觸發進入Grievous Lady時，為真實Hard模式。
- 上傳一次成績後，更迭分兩種情況：
- Potential為通過聯網計算再獲取返回值，在多設備登陸的情況下會出現多次上傳成績，因此有的截圖並不符合上述規則
單次成績ptt計算
| 分數 | 單次成績ptt |
|---|---|
| ≥ 10,000,000（即PM） | 定數+2 (此時屏蔽物量影響) |
| ≥ 9,800,000 且 < 10,000,000 | 定數+1+(分數 - 9,800,000)/200,000 |
| < 9,800,000 | 定數+(分數 - 9,500,000)/300,000 (下限為0) |
所以說，單次成績ptt為0的通式為
分數 ≤ 9,500,000 - 定數 × 300,000
總的來說，單次成績ptt與分數的關係見下
| 分數 | 單次成績ptt |
|---|---|
| 10,001,450 | 定數+2.00 |
| 10,000,000 | 定數+2.00 |
| 9,950,000 | 定數+1.75 |
| 9,900,000 | 定數+1.50 |
| 9,800,000 | 定數+1.00 |
| 9,500,000 | 定數 |
| 9,200,000 | 定數-1.00 |
| 8,900,000 | 定數-2.00 |
| 8,600,000 | 定數-3.00 |
單次成績ptt下限為0
| v3.0.0之前的單次成績ptt計算公式 | |
|---|---|
| 分數 | 單次成績ptt |
| ≥ 10,000,000（即PM） | 定數+2 (此時屏蔽物量影響) |
| ≥ 9,950,000 且 < 10,000,000 | 定數+1.5+(分數 - 9,950,000)/100,000 |
| ≥ 9,800,000 且 < 9,950,000 | 定數+1+(分數 - 9,800,000)/400,000 |
| < 9,800,000 | 定數+(分數 - 9,500,000)/300,000 (下限為0) |

| 歷史回溯法(choka法) |

| STEP法(robert法) |

| 數據回溯法(Xecus法) |
|---|
| 原理：使用了lowiro的api，返回的是精確數據
通過訪問api來獲得最近分數以及對應ptt，由公式反推獲得定數 優點：一次算出，精度最高 缺點：只能查到最近遊玩成績對應ptt |
研究過程與驗證
- 根據JPwiki Arcaea的FANDOM wiki中Potential頁面的算法，ptt由best30和recent30中的top10構成
- v3.0.0之前的EX保護機制
- 在現有ptt計算準則條件下，有關recent的記錄常常有一定出入，在某一單曲得分對應ptt低於現有總ptt平均分時，有些情況顯示keep而有些情況會產生扣分，由此推測對於recent的記錄是有選擇性的。
- 根據robert_cpp的計算表附加說明，「持續得到EX評價時無關曲目的其餘任何條件，ptt會始終保持keep結算。」
- 有理由認為recent的記錄出入與是否得到EX評級有關。
| Vanitas的掉分實證推論過程 |
|---|
| 先放置清空recent（結算根據是：當前ptt=30個best總成績之和/40，說明recent總和為0。）
24次FTR EX(無PM)外加高定數曲目5次AA和1次標記項目，且計入ptt計算的10次recent得分(含AA項)偏差值在±0.4以內， 再持續獲得30次PST/PRS的EX+FR時，ptt始終保持keep，下一步即第31次完成標記項目(SOUNDWiTCH FTR半放置等效得分8.4，小於上一步最後成績得分Sheriruth PRS(9.7)) 同時成績嚴格小於前30pc任意一次； 此操作過後立即開始30次放置掉分，結果顯示在前20次放置中ptt整體減分有0.05，主要減分階段在最後10次； 結果以及分析結論 標記項目得分8.4的成績在最後被去除(-0.21)， 9.8 說明10項最高recent記錄並不會被最後整理至寫出隊列尾部，而是依舊保持日期順序。(否則前20次不會掉分) 最後10次任一減分對應單曲成績(-0.27±0.01)均大於上一步所達成的全部次難度成績 由此可知PST/PRS EX的任何記錄沒有寫入到recent。 推論是：對於任何EX評級的成績，如果將其寫入recent隊列會導致ptt下降，則該成績並不會寫入隊列，而是直接捨棄，故將其稱為「EX成績寫入保護」。 【並不是一度認為的EX recent成績一定會被保留的觀點】 此機制的存在可以充分解釋為何h1r、higllus等人為何在最後集體刷全難度理論值時並不會因為recent記錄一些交替而導致掉分，因為在EX後的記錄如果成績太低並不會寫入recent。 至於掉分的情況的論證則很簡單，五月初爬梯子只打Blaster連續15次不足EX就突然被扣了0.02，五月二十日conflict推分掉ptt截圖在推特可見 對於爬分玩家而言，此機制的存在相對避免了了斷網保分的極端措施，EX之上即可獲得保險 |
- PM保護機制證偽說明(2018.06.29)：由RichadoWonasas的掉分個人證明，其ptt在recent為0的情況下為8.80，等效為11.73平均分。
- 掉分前已PM過Cybernecia Catharsis，當時定數為9.8，PM得分11.8>11.73。
- 很明顯若PM具有強制保留機制的話那麼其放置30次的結果應大於recent為0即8.80的情況，故PM強制留存記錄的機制不存在。
- Blurring Shadow發現了Xecus的機械人可以查詢單次遊玩的ptt後，聯繫了頁面編輯者Vanitas和RichadoWonasas進行相關實驗，修正了單曲ptt計算係數
- 一些定數勘誤有【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（均為v3.0.0之前的定數）
- 關於v3.0.0之前9,800,000 - 9,949,999分數段內的變化率比例（即，這一段分數內PTT增長率與9,800,000分以下的PTT增長率的比值）為0.75的證明可參照RichadoWonasas的專欄PTT研究附錄：一個被誤算了許久的比例。
