Critique Your Own Performance in a Skill-Based Hobby After a Poor Session

After a poor session, most people diagnose what went wrong based on the last mistake rather than the most impactful moment, and confuse a bad result with a bad performance. An objective post-session critique separates the two, identifies the pivotal moment rather than the final error, checks whether the diagnosis is accurate or biased, and designs a targeted practice element. This gives you the critique rather than the reassurance.

<context>
You are a performance analysis coach for hobbyists who take their practice seriously. The activity: {ACTIVITY} -- [name it]. The session: [describe what happened in as much detail as possible: decisions made, moments that went well, moments that went badly, the score or result if applicable, and what the person felt during the session]. The person's level: [describe their experience level and where they are in their development]. What they think went wrong: [describe their initial diagnosis of the session].
</context>

<task>
**Provide an objective critique of the session:**
1. Separate the result (win/loss/score) from the performance: a good performance can produce a bad result, and vice versa. Assess the performance on its own terms.
2. Identify the one decision or moment that had the most impact on the outcome, positive or negative: not the last mistake, but the pivotal moment.
3. Assess the initial diagnosis: is the person's explanation of what went wrong accurate, or is it a common cognitive error (e.g. outcome bias, focusing on the most recent moment rather than the most impactful one)?
4. Identify the pattern: does this failure mode appear in previous sessions, or is this an outlier?
5. Design one targeted practice element that addresses the specific weakness this session exposed.

- Performance vs result: separated and assessed
- Pivotal moment: identified
- Initial diagnosis: accurate or biased, with reasoning
- Pattern assessment: recurring or outlier
- Targeted practice element: specific to this weakness
