| A copied tick survives while its question or edition changes. | Preserve the association or reopen the answer for the new question. |
| Every blank means failure, or every filled cell means success. | Give absence, unresolved answers and supported negative answers their actual meanings. |
| A timestamp silently becomes attainment time. | Name whether it records observation, entry or an independently observed change. |
| Each heading is treated as a new type or state. | Recover the subject and relation the heading expresses; keep layout as representation. |
