Numbers reported different for LSS

[Vikr-182]

Hi.
Thank you for your work. I had a query about the results on NuScenes.
The numbers reported for Lift-Splat-Shoot (LSS) for Car is 32.06 by the original authors and 27.3 by the your work. Drivable area is reported 72.04 by the original authors, and 55.9 by your work.
What are the possible reason for this?
Can you also specify the train/val split used in NuScenes? Thanks.
