Copy the decision log. Keep the original record.
Use this CSV template before an event. Add the result and review note later without changing the original fields.
| Date created | Event | Selection | Reference line or price | Sources checked | Source timestamps | Reason it qualified | Material uncertainty | Planned pick size | Sizing rule | Result | Review note |
|---|---|---|---|---|---|---|---|---|---|---|---|

What this decision log is for
A decision log preserves what you knew, what you inferred, and what you planned before the result can influence your memory. It turns a sports prediction into a reviewable record instead of a story reconstructed after settlement.
The template is deliberately short. A record you can complete every time is more useful than a detailed worksheet used only for the most memorable events.
Record facts, interpretation, and uncertainty separately
Use the source and timestamp fields for information you can identify later, such as a published schedule, official availability update, or recorded reference line. Write your interpretation in its own field so it does not become confused with the source fact.
The uncertainty field is equally important. Name the information that is late, incomplete, or could change the decision. A clear unknown is more useful than a confident explanation added after an outcome.
- Event, selection, and the time the record was created.
- Sources checked and the time each source was checked.
- Two or three reasons the selection met the stated process.
- One material risk, missing input, or invalidation condition.
- Planned pick size and the rule used to choose it.
Do not rewrite the original entry
After the event, add a dated result and a short review note. Do not replace the original reasoning or planned size. If meaningful information changed before the event, add a clearly marked follow-up note rather than editing history.
This makes it possible to inspect whether a weak result came from missing information, a weak interpretation, a size that drifted from the plan, or normal uncertainty. A single result does not establish that a process will work in the future.
Use the template with published challenge rules
A decision log can organize your own research and review, but it does not determine challenge eligibility. Polyfunded measures predictions with a virtual balance under published 1-Step Challenge rules; it does not accept wagers or provide a betting wallet.
Before participating, check the current Rules, Pricing, and final challenge brief. Targets, loss limits, pick requirements, consistency checks, review, and Reward Stage eligibility are governed by those materials.
