feedback arriving within the window but too late for the correction to land before the next drift.

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [feedback](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-feedback.communication), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [late](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-late.temporal), [next](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-next.temporal), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [land](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-land.geography)

**Through:** The interaction of feedback, drift, temporal sequencing, a persistence window, and the notion of corrective arrival upon a parameter state enables feedback to arrive too late for correction before the next drift.

**Novel properties:**
- untimely correction
- arrival within bounds but after need
- drift-correctable window

## Examples
- In the 2012 Knight Capital trading glitch, feedback from delayed stock price updates arrived too late to prevent erroneous trades piling up in under 45 minutes. *(computing)*
- The Therac-25 radiation therapy machine administered lethal overdoses because software feedback about beam intensity arrived after the next cycle had already begun. *(engineering)*
- During the 2008 financial crisis, credit rating updates for mortgage-backed securities lagged behind actual defaults, missing the window to adjust investor behavior. *(economics)*
