2. 平均KD值（每局）
3. 平均KAST（每局）
4. 平均RWS（每局）
5. 每局爆头击杀数
6. 爆头率（爆头击杀/总击杀）
7. 每局首杀次数
8. 每局首死次数
9. 首杀率（首杀次数/首遇交火次数）
10. 首死率（首死次数/首遇交火次数）
11. 每局2+杀/3+杀/4+杀/5杀次数（多杀）
12. 连续击杀累计次数（连杀）
15. **(New) 助攻次数 (assisted_kill)**
16. **(New) 无伤击杀 (perfect_kill)**
17. **(New) 复仇击杀 (revenge_kill)**
18. **(New) AWP击杀数 (awp_kill)**
19. **(New) 总跳跃次数 (jump_count)**
---
## 挖掘能力维度：
### 1、时间稳定序列特征 STA
1. 近30局平均Rating（长期Rating）
2. 胜局平均Rating
3. 败局平均Rating
4. Rating波动系数（近10局Rating计算）
5. 同一天内比赛时长与Rating相关性（每2小时Rating变化率）
6. 连续比赛局数与表现衰减率（如第5局后vs前4局的KD变化）
### 2、局内对抗能力特征 BAT
1. 对位最高Rating对手的KD差（自身击杀-被该对手击杀）
2. 对位最低Rating对手的KD差（自身击杀-被该对手击杀）
3. 对位所有对手的胜率（自身击杀>被击杀的对手占比）
4. 平均对枪成功率（对所有对手的对枪成功率求平均）
* ~~A. 对枪反应时间（遇敌到开火平均时长，需录像解析）~~ (Phase 5)
* B. 近/中/远距对枪占比及各自胜率 (仅 Classic 可行)
### 3、高压场景表现特征 HPS (High Pressure Scenario)
1. 1v1/1v2/1v3+残局胜率
2. 赛点（12-12、12-11等）残局胜率
3. 人数劣势时的平均存活时间/击杀数（少打多能力）
4. 队伍连续丢3+局后自身首杀率（压力下突破能力）
5. 队伍连续赢3+局后自身2+杀率（顺境多杀能力）
6. 受挫后状态下滑率（被刀/被虐泉后3回合内Rating下降值）
7. 起势后状态提升率（关键残局/多杀后3回合内Rating上升值）
8. 翻盘阶段KD提升值（同上场景下，自身KD与平均差值）
9. 连续丢分抗压性（连续丢4+局时，自身KD与平均差值）
### 4、手枪局专项特征 PTL (Pistol Round)
1. 手枪局首杀次数
2. 手枪局2+杀次数（多杀）
3. 手枪局连杀次数
4. 参与的手枪局胜率(round1 round13)
5. 手枪类武器KD
6. 手枪局道具使用效率（烟雾/闪光帮助队友击杀数/投掷次数）
### 5、阵营倾向（T/CT）特征 T/CT
1. CT方平均Rating
2. T方平均Rating
3. CT方首杀率
4. T方首杀率
5. CT方守点成功率（负责区域未被突破的回合占比）
6. T方突破成功率（成功突破敌方首道防线的回合占比）
7. CT/T方KD差值（CT KD - T KD）
8. **(New) 下包次数 (planted_bomb)**
9. **(New) 拆包次数 (defused_bomb)**
### 6、道具特征 UTIL
1. 手雷伤害 (`throw_harm`)
2. 闪光致盲时间 (`flash_time`, `flash_enemy_time`, `flash_team_time`)
3. 闪光致盲人数 (`flash_enemy`, `flash_team`)
4. 每局平均道具数量与使用率（烟雾、闪光、燃烧弹、手雷）
