I find that the Garmin Connect Web and IOS Health & Performance Comparison Reporting need improvement. Even the Apple Health App does a better job than Garmin through their Health Trends and Highlights Reporting.
The data is there, but the reporting needs to be improved.
Also, the IOS Home presentation of data in enormous rectangular blocks is horrible visually and greatly reduces the amount of data that can be seen without having to scroll too much up and down - see pics below
