If you're saying 2000 is much greater than 1300, it's not that straightforward.
FR/ADS-B altitude is Pressure Altitude (29.92 inHg). Need to add about 220 ft to correct for local pressure (VNY altimeter 30.16).
Ceiling is AGL. Elevation at 101 & Las Virgenes is ~800 ft.
But the ceiling in the mountains could be very different than the ceiling quoted by VNY ATC.
NY Times quoted witnesses saying the clouds were 300 ft AGL at the time of the crash.

The timing is just right. If the ADS-B data is to be fully believed, they were already in a 2000+ ft/min descent and 45 degree or so bank at that point.
There may have been multiple doorbell cam videos, but the one I saw started at 9:45:01 am PST, which was +1280 fpm ascent at that time.
