There is a Hybrid update available that increases the accuracy of timings by improving the stability of frame rates. The improvement is a faster decryption algorithm that works with the sdcard. The difference is significant especially if you are getting early predictions and using the target equivalent. But the downside is the sdcard needs a firmware update so it needs to be sent back to me. It cant be done remotely as it uses coded hardware only I have. If you ship it back, remember to use a reputable courier that tracks is all the way, and contact me for the address you need to send to (not the po box).
Any of the future updates will need the firmware update so you will need to send the card back anyway at some stage. We tried to avoid this being needed, but the rare exception is the firmware update.
