Correct. While you can plot a reasonably accurate profile (altitude vs horizontal position) from the FR24 data, you can't reliably derive anything that's time-dependent as the timestamps (added to the ADS-B data by FR24) are all over the place.
Anyone who doubts that is invited to try to calculate groundspeed by dividing the distance between two successive plots by the interval between the associated timestamps.
