Does the 30 second power gauge work for anyone

Hi I added the 30 second power gauge to videos I am making, and despite the real time power being absolutely perfect, the 30 second power appears to be around 30 seconds AHEAD of where the power is. So if I am coasting before doing a 30 second sprint, the real time power gauge shows 0, while the 30 second power increases like crazy while I am not even pedaling. Anyone else seeing this? Yes i know the software is dead
