Keep recorded and draft estimates distinct
Synthetic T-191 has six actual hours and four recorded remaining hours, forecast ten. The original estimate was eight. A local number draft starts at four with nonnegative half-hour steps; it does not recalculate or save the recorded forecast.
| Input or inspection | Expected view | Business meaning |
|---|---|---|
| Read recorded forecast | 6 actual +4 remaining =10 | Original8 retained separately |
| Enter −0.5 or 0.25 | Input constraint invalid | Nonnegative half-hour steps |
| Edit draft to3 | Draft3; recorded remainder4 | Recorded forecast still10 |

Two hours: ten minus eight. The draft input does not change that recorded comparison.
Actual work hours are retained rather than overwritten by a new planning assumption.
