When I compare wind speed (km/h) in the web, android app and Weather Underground (WU), there are mismatches. I understand that the zoom factor applied affects the averaging per time unit displayed for a given device. However the web data in this - admittedly - small sample never gets beyond 13 km/h for gusts, whereas WU will show gusts up to 36.4 km/h and the android app has several hits above 40 km/h. No zoom factor combinations can provide better agreement between devices. Can somebody please explain to me why the web data differs so much from the other two devices. ![firefox_2019-01-20_11-33-37](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex020/uploads/sws/original/2X/e/e92d8ace746680f9da94f9d4a42959528c92e1c7.png) ![Screenshot_20190120-113240_Smart%20Weather](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex020/uploads/sws/original/2X/7/7f172ab4a66f5304bb278d6cddb3fa2afeae2c19.jpeg) ![firefox_2019-01-20_12-15-34](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex020/uploads/sws/original/2X/7/78339fcf4f2ebb242a0b3518980b2874bec93255.png) ---
