Gradistat V 91 Hot Page
is a widely used computer program designed for the rapid analysis of grain size statistics from unconsolidated sediments. Originally developed by Simon J. Blott and Kenneth Pye in 2001, it operates as a Microsoft Excel-based package
The first is technical: the macro ran hot — meaning it pushed Excel’s VBA engine to its thermal limit. Laptops would heat up noticeably during batch processing. One geologist recalls his Dell Latitude shutting down mid-session, the screen going black with a single line of on‑screen text: “Gradistat v.91 Hot exceeded system resources.”

The Good
- Performance Boost: The "Hot" moniker isn't just marketing fluff. Version 91 feels significantly snappier than previous builds (such as v 88 or v 90). Data processing times seem reduced, and the interface responds instantly to inputs, even with heavier datasets loaded.
- Expanded Compatibility: This version seemingly resolves several dependency issues found in older branches. It integrates smoother with modern environments (depending on your specific use case), making it more stable on newer hardware/OS setups.
- Feature Density: For advanced users, the new syntax shortcuts and menu options are a godsend. It allows for granular control that was previously missing, cutting down workflow time considerably.
