Miles,
The max score for each workload was calculated by assuming zero SUT response time (e.g., the theoretical maximum score that could be achieved by an 'infinitely fast server').
See section 1.3 of the Design Guide. ....specifically:
"We calculate the overall score by taking each component workload in each tile and normalizing it against its theoretical maximum for the pre-defined load level. The normalized throughput scores for each tile are averaged arithmetically to create a per-tile submetric, and the submetrics for all tiles are added to get the overall performance metric. The SPEC virt_sc metric includes reporting this overall metric along with the total number of VMs used."
