About

Wind Correction

Read full description

In athletics, wind conditions are a crucial factor for every athlete. Wind Correction is the first app that lets you accurately calculate what your time or measurement would have been under any desired wind conditions. Wondering how your performance might change with a neutral wind? Or curious to see your potential with a more favorable breeze? Simply select your event, input your recorded result along with the wind conditions you experienced, and choose the wind value you want to test. Wind Correction will do the rest! The app’s algorithm is based on the studies and research of M. Moinat, O. Fabius, and K.S. Emanuel. Their findings were published in 2018 in the article, Data-Driven Quantification of the Effect of Wind on Athletics Performance.
