This is true, but having an idea for what a node should give you and running HPL on each node and comparing can reveal poorly performing nodes (say due to BIOS/UEFI issues) and that will have knock on effects for real codes if you are running tightly coupled MPI jobs or are doing timing runs whilst tuning and you end up on a bad node. cheers!
