当场会弹、隔天记得、换条件能用
刚重复过一个句子，马上弹对，并不回答“下次能否自己想起”。例如把 C4 D4 E4 G4 E4 C4 各弹一拍：今天练完的最后一次、下次练习的第一次，以及从 G4 开始的那一次，应分开记录。
先认识拍与音名，再做实验 E12。这三个问题可分别叫作当场表现、保留（retention）与迁移（transfer）。这里把它们当作观察任务，不给学习效果作保证。
来源提出了什么问题
【作者观点】Chang 在 FOPP-23 区分练习中立即变化与停止练习后的变化，并使用 PPI（Post Practice Improvement）这一名称。已读本节英文，核对实际PDF第52–55页相关正文；节首印刷页为51。这个区分提醒我们不要只看最后一次尝试。
【作者观点】FOPP-14 建议从记忆中的不同位置进入，并用结构线索检查背谱；实际第32、36页相关正文已核对。Wiwi 关于乐谱减轻记忆负担的观点见读谱笔记。两者的取向不应合成“学会之后一律不看谱”的规则。
怎样留下可解释的记录
【本库综合】记录是否看谱、有没有先听参考、起点、速度、错误位置和额外停顿。下次先测一次，再继续练；否则再练之后的结果会混入本次热身。改变起点或音区后另记一行，不把它混进相同条件的保留结果。
【本库综合】一次变好或变差仍可能受提示、熟悉程度、精力和测量方式影响。不要从自己的两次弹奏，直接推出睡眠造成进步或某个生理机制已经成立。练习日志可帮你提出下一次的问题，不能代替机制研究。
不采用哪些保证
【证据边界】§23 对统一练习分钟数、最低重复量、细胞变化、睡眠清除坏习惯及呼吸助眠有具体主张。本轮没有完成独立科学或医疗核验，本库不把这些解释、阈值或呼吸方案改成初学者处方。PPI在这里是作者用语，不表示已证实的统一生理过程。
下次表现变化，不急着指定原因
【作者观点】FOPP-27用FPD描述快弹之后下次表现变差的情形，并给出练法建议；它的机制解释属于作者推测。Wiwi的练习文章建议不要在单一材料上无限重复，同时对睡眠后的改善给出较强描述。
【本库综合】记录本次结束与下次开始的速度、起点、错误和是否看过提示，才能知道比较了什么。安排休息或轮换材料后没有立刻进步，也不能仅凭一次结果判定学习失败。这里不承诺睡一觉必然改善，不以手脑“混乱”诊断原因；回到E12。
灵感出现之后，仍要检查结果
【作者观点】FOPP-72以个人解题经历讨论停止用力思考后出现的新想法。中文选段大体保留原意；“一半人的潜意识更聪明”等统计与脑机制断言未被本轮证实，不能从作者的经历直接推出。
【本库综合】卡住时可以先留下具体问题：哪个连接、什么速度、哪次尝试发生了什么。之后有新办法，按相同目标再试并记录差异。新想法可能有用，也可能无效；回访结果不能单独证明是哪一种大脑机制在起作用。
Playing it now, retaining it later, using it under new conditions
Correctly playing a phrase just repeated does not answer whether you can retrieve it next time. For C4 D4 E4 G4 E4 C4, one beat per note, record today's final attempt, the first attempt next session, and an attempt starting at G4 separately.
Learn beat and note names, then try E12. These questions concern immediate performance, retention and transfer. They are observation tasks here, not guarantees of learning effects.
Questions raised by the sources
[Author's view] FOPP-23 distinguishes immediate practice changes from changes after stopping and calls the latter PPI, Post Practice Improvement. Its English section was read; relevant actual PDF text on physical pages 52–55 was checked. Its opening printed label is 51. This distinction invites checking more than the final attempt.
[Author's view] FOPP-14 recommends entering at different remembered locations and using structural cues to check memory. Relevant physical pages 32/36 were checked. Wiwi's view of scores reducing memory burden appears in reading. These approaches must not become a universal rule to stop using notation once a piece is learned.
Make the record interpretable
[Our synthesis] Record score access, prior reference sound, start, speed, error locations and extra pauses. Test once before practicing again next session; otherwise warm-up enters the result. Give changed starts/registers separate rows rather than treating them as retention under identical conditions.
[Our synthesis] A better or worse attempt can still reflect cues, familiarity, energy or measurement. Two personal attempts do not establish that sleep caused improvement or that a physiological mechanism is valid. A practice log generates the next question rather than replacing mechanism research.
Guarantees not adopted
[Evidence limits] Section 23 makes specific claims about uniform practice minutes, minimum repetition, cell changes, sleep removing bad habits and sleep-inducing breathing. Independent scientific/medical verification is unfinished. These explanations, thresholds and breathing procedures are not beginner prescriptions here. PPI remains the author's term, not an established single physiological process.

A changed result does not identify its cause
[Author's view] FOPP-27 calls poorer performance after fast playing FPD and recommends practice changes; its mechanism is the author's hypothesis. Wiwi's practice article advises against endless repetition of one item and makes strong claims about improvement after sleep.
[Our synthesis] Record tempo, starting point, errors and access to cues at the end of one session and the start of the next. Otherwise the comparison is unclear. Lack of immediate improvement after rest or switching material does not establish failure from a single result. We promise no overnight improvement and do not diagnose hand/brain confusion. Return to E12.
An idea still needs a result check
[Author's view] FOPP-72 uses personal problem-solving experiences to discuss ideas arising after deliberate effort stops. Selected Chinese passages broadly retain the meaning. Statistical and neural claims, such as half of people's subconscious being smarter, are not established here and do not follow from those anecdotes.
[Our synthesis] When stuck, record the specific join, tempo and observed attempt. If a new approach comes later, test it against the same goal and record the difference. The idea may help or fail; a follow-up result alone does not establish which brain mechanism caused it.
