RunScope — the progress bar that doesn't lie

Field notes

RunScope is designed for enumerable workloads whose future items are already available, such as files, records, images, simulations, and parameter grids. Its examples show a tqdm-compatible Python interface and an ETA expressed as a range, including 1h12m–1h31m for a loop 17,492 items into a 48,000-item run. The page attributes its sampling method to Horvitz-Thompson estimation and says the tool declines to invent an estimate when the workload cannot be assessed honestly.
