Btw I compared FR24 data with Flightaware data. They seem to be from different sets of ADS-B receivers (possibly overlapping), but the data over the runway match within +/- 25ft altitude and < 100m position along the centerline. I.e., both show the aircraft well above where it should have been, well past the runway threshold.
The two sources are consistent, but that doesn't mean they are accurate.
We have already seen in a previous post (#19) that, based on the QNH in the METAR, the aircraft would have been reporting heights roughly 300' lower than actual.
RoD will, of course, be the same as implied by the ADS-B data.
