Question: Incorrect “Speed (GPS vehicle speed, m/s)” Value?

I've noticed that the “Speed (GPS vehicle speed, m/s)” parameter shows an incorrect value. For example, when my actual speed is 25* km/h, the SDK reports 7* m/s, which is 11* km/h.

Interestingly, another overlay that also uses the iRacing SDK shows 16 m/s at the same moment, which correctly corresponds to 25 km/h.

I've attached a video demonstrating this discrepancy. Can anyone explain why this happens? Is the SDK returning incorrect data or using a different calculation method?

Thanks!

This is how it works

speed = self.ir['Speed']
speed_kmh = speed_m_s * 3.6
speed_mph = speed_m_s * 2.23694
