I'd really like to see the recovery adviser value in Garmin connect and some means of handling recovery adviser values coming from multiple devices. I have two devices with the Recovery Adviser feature the Forerunner 630 and an Edge 1000. i.e. one for running and the other for serious cycling. It's a pain to go and check each device directly.
I have found the feature very useful. When I have been feeling a bit under the weather the recovery adviser has also picked up on this and I have been able to continue training at a reduced level until the minor illness e.g. cold has passed.
