Live Flight Tracking

Could the track lines be a different color where there is a gap of more than the 'expected' (whatever that is) interval for the data. Then it would be apparent on the map which parts of the routing were interpreted rather than driven from the data. There are several comments about people (on other forums) flying IFR routes that have turns in them but when shown on flightaware, it appears like a straight line (examining the data in one case explains this because there is a 1 hour interval in the track log where no data has been recorded; so a straight line appears from the previous point to the new point - it is this line that should be a different color.
