Catch-up can mask strain
A strong later week may bring the total close to plan while leaving an earlier missed week unexplained. The period ledger preserves that timing.
Education
Reconcile planned and completed pages across an ordered weekly log, including catch-up, over-plan, and worst-week signals.
READING PLAN COMPLETION
A single completion number can hide a missed week or a late catch-up. Enter the ordered plan and actual page counts to preserve the weekly variance and cumulative story.
LIVE DECISION VISUAL
Use the worst period to diagnose schedule friction and the total completion to decide whether the remaining plan needs a new deadline or a smaller scope.

LIVE CALCULATION PROCESS
planned total = Σpᵢ; completed total = Σcᵢ; completion = completed total ÷ planned total × 100; varianceᵢ = cᵢ − pᵢ
HOW TO USE
SUBJECT FUNDAMENTALS
CALCULATION METHOD
Defaults give P = 60+70+80+90 = 300 pages and C = 55+72+68+40 = 235 pages. Completion is 235÷300×100 = 78.33%, remaining pages are 65, and weekly variances are −5, +2, −12, and −50. The fourth period is the weakest.
DEEP ANALYSIS
A strong later week may bring the total close to plan while leaving an earlier missed week unexplained. The period ledger preserves that timing.
Completion above 100% may mean extra reading, a revised scope, or a denominator error. The page labels overage instead of clipping it.
A negative week could reflect illness, workload, text difficulty, or a logging error. Use it to ask a question, not to assign blame.
RESULT INTERPRETATION
A total below 100% means planned pages remain under the entered denominator. A total at or above 100% means the plan was met or exceeded, but it does not prove that the pages were understood. The bars show the timing pattern behind the headline.
The weekly chart is current-value data from the two lists. It can mislead if periods use different lengths or if completed pages were logged after the period ended.
EVIDENCE AND DATA LINEAGE
Save the syllabus or reading plan, period dates, edition/page range, and timestamp of each progress entry. If a week is edited after the fact, retain the prior snapshot so the change is auditable.
LIMITS AND EXCLUSIONS
TECHNICAL GLOSSARY
WORKED DECISION CASES
A single large negative variance may justify moving a deadline or splitting the next reading assignment, even if the total completion looks acceptable.
Repeated negative variances suggest the weekly plan is too large or the period capacity assumption is wrong. The response should change the plan, not only the motivation message.
IMPORTANT NOTE
If the reading scope changes, start a new plan version and keep the old ledger as evidence of the original decision.
FREQUENTLY ASKED QUESTIONS
Yes. The page reports over-plan pages because extra reading is evidence, but it does not redefine the original completion denominator.
A zero is meaningful for a missed period. A blank record is rejected because it could hide missing data.
No. Each planned period needs a corresponding completed record so order and variance remain interpretable.
No. It means the page count reconciles. Add comprehension or retrieval evidence for readiness.
It identifies the largest positive variance, which may show catch-up or an unusually light assignment.
