One of the few things that's always bothered me about Garmin Connect is the inability to filter out data outliers. I have a FR70 with the footpod, and there's usually a start-up spike of either a very slow or very fast pace, resulting in a scale on the pacing chart that is extremely compressed. If that nonsense data point could be filtered out within Connect, it would make the charts immensely more useful.
Here's an example from my recent 5k. You can get the precise paces at any point by hovering over the line, but it's pretty much worthless visually.
