OP if you're that competitive that you care about correct recording of your group ride 'attacks', it's time to pin a number on and ride against some others who care about winning. Your group ride buddies probably just let you ride on your own while they concoct schemes for doctoring their Strava files to mess with your head.
Agreed to the OP on maybe this type of workout isn't really for the day you go on a group ride. As far as how hard it would be to doctor raw GPS files? Depending on which device is used and how he gets that data into strava, doctoring a file isn't that hard if .gpx or something similar is used in the middle - if the other rider mysteriously jumped in front of the OP on his last 'breakaway' (on a group ride? why not just train by yourself?), he's probably yanking his chain. Especially if everyone else who was on the group ride logs in and 'kudos' the mystery rider.
