Armitage (online 2024; issue 2025). On Lateness: The Ethics of Running Behind Schedule in General Practice. Summary: Delays burden other people, but rigid punctuality or rushing to catch up can conflict with care and equity. Citation: Richard C. Armitage (online 2024; issue 2025). On Lateness: The Ethics of Running Behind Schedule in General Practice. Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC11664903/ Material reviewed: Open article, substantive sections reviewed. Scope: A clinical ethics analysis, not general performance evidence. S7 interpretation: Pair realistic buffers with compassion; do not encourage rushing important work. ### Roger Buehler, Dale Griffin & Michael Ross (1994). Exploring the Planning Fallacy: Why People Underestimate Their Task Completion Times. Summary: People underestimated their own task durations. Relating relevant past experience to a current task reduced optimistic bias. Citation: Roger Buehler, Dale Griffin & Michael Ross (1994).

Source: https://eprints.whiterose.ac.uk/id/eprint/87431/ Material reviewed: Author-repository abstract and publication metadata reviewed. Scope: Monitoring progress differs from manipulating the displayed time. S7 interpretation: Compare actual completion, quality and stress rather than relying on a subjective impression. ### Sven Thönes, Stefan Arnau & Edmund Wascher (2018). Cognitions about time affect perception, behavior, and physiology: A review on effects of external clock-speed manipulations. Summary: Altered external clocks can change perceived time and some behavioural or physiological outcomes. Citation: Sven Thönes, Stefan Arnau & Edmund Wascher (2018). Cognitions about time affect perception, behavior, and physiology: A review on effects of external clock-speed manipulations. Source: https://pubmed.ncbi.nlm.nih.gov/29966862/ Material reviewed: Indexed abstract reviewed. Scope: Varied tasks and manipulations do not establish a universal benefit.

PV function. Microsoft Support. Source: https://support.microsoft.com/en-us/excel/functions/pv-function Summary: Present value relates a future amount to a chosen interest rate and duration. Payment frequency and rate units must be consistent; the timing of recurring payments also matters. Scope: PV syntax, rate/time consistency and payment timing sections reviewed on 11 October 2026. Limit: A calculation reference, not evidence that a chosen investment return will occur. S7 uses an assumed effective annual return and actual remaining date interval for goal weights. S7 interpretation: Explain the discount assumption and distinguish current-value goal importance from the actual investment portfolio. ### U.S. Securities and Exchange Commission (n.d.). Compound Interest Calculator. Investor.gov. Source: https://www.investor.gov/financial-tools-calculators/calculators/compound-interest-calculator Summary: Initial savings, regular contributions, time, an assumed interest rate and compounding frequency shape an illustrated future balance. Changing these inputs changes the projection. Scope: Educational calculator inputs and compounding options reviewed on 11 October 2026. Limit: Educational illustration, not a guarantee or a measure of realized investment performance. S7 separately states its month-end contribution and partial-month assumptions. S7 interpretation: Keep projected funding, the year-end target and dated actual earmarked values distinct.
