how the ROI reports are calculated
the assumptions behind every figure, in plain words. illustrative estimates, not a promise of results.
the adoption ramp
a team does not hand over all of its eligible work on day one. the model raises adoption quarter by quarter in year 1, and full adoption is never all of the work.
wages and benefits
each role’s hourly wage comes from the Bureau of Labor Statistics, raised to the employer’s full cost of a person, benefits included.
evidence grades
every task’s by-hand hours rest on evidence graded A (strongest), B or C (weakest). the weaker the evidence, the more the value of the time returned is reduced.
capacity, not cash
- returned hours are capacity your team can use; they become savings only when they replace a hire, overtime, temps or outside spend.
- hourly firms cannot bill time saved.
the cap on returned hours
returned hours for any one role are capped at a share of the month; grade-C volume is trimmed first.
estimated professional time returned
the subscription page estimates the professional time Prest0n returns from the items a month finishes, at this time per item: how: for every task given to Prest0n (the tasks kept by hand left out), its hours returned (the hours by hand minus briefing, review and the chance of a redo, never below zero) are split across the items it produces in proportion to their pr0; each kind’s hours are then divided by its number of items, weighted by how often one full-time person does the task, across every task of the four industries. a portal task counts as three task turns. capacity, not cash; an estimate for planning.
what these figures are
illustrative estimates, not a promise of results. what your firm sees depends on its work, its people and how much of that work it hands to Prest0n.

the assumptions
- adoption in year one, by month: 25%, 25%, 25%, 50%, 50%, 50%, 75%, 75%, 75%, 90%, 90%, 90%; steady adoption 90%.
- a full-time person works 155 hours a month; returned hours per role are capped at 25% of the month.
- evidence haircuts: grade A 10%, grade B 20%, grade C 35%.
- wages: BLS OEWS, May 2025; compensation: BLS ECEC, June 2026.
modeled estimates from the open ROI report, version 2026-10, prices as of 9 October 2026. returned hours are capacity, not cash; these are modeled, not guaranteed, and not a promise of results.
