Not for me it isn't. Especially if you prefer the 18" wheels and standard suspension for general road use. I can only see the point in buying the P if you are going to be doing regular track days in it.
Given the aim of this test, I very much doubt it was. It would have also matched the P off the line. The result looks like every other LR vs P drag test I've ever seen i.e. P getting a good jump from a standing start and then not much more. Even closer from a rolling start and nothing in it above 60 mph.
I suspect there will be a software upgrade along at some point to ensure the refresh P's performance is on a par with the pre-'21 cars.
looks like some dodgy editing, however it does show that the P, IMO is not worth the extra over the LR
