Performance test charts should show the best performing as 100%

I understand you guys are a business and want to make arango look good. Having arango fixed to 100% makes it appear like the most consistently performing database. Though it also makes the benchmark appear more biased than it needs to be.

Either way thanks for making this benchmark, there's a lot of talk on this topic and not enough measurement.
