What are the key differences between ANT+ and Bluetooth power meter connectivity when using a bike computer to track power output and performance, and how do these differences impact data accuracy and reliability, particularly in high-interference environments or when using multiple devices simultaneously? Do the majority of modern bike computers support both ANT+ and Bluetooth power meters, or are there still compatibility issues that need to be considered when selecting a bike computer and power meter combination? How do factors such as data sampling rate, signal strength, and device pairing impact the overall performance and accuracy of power meter data, and are there any best practices for optimizing these factors to ensure reliable and accurate power data?
