I don't get where this 50% comes from? When I take the full list of the prices (https://aws.amazon.com/emr/pricing/), I get as low as 1,10% EMR cost for p3.16xlarge and the highest is 30,77% for g2.2xlarge.
There's a bunch of instance types that don't make sense in an EMR cluster, in my experience the EMR markup is rather ~10-15% on average, which seem rather OK for the service it offers.
