Are you concerned about using `Infinity` for local dynamo or the `0.8` factor?

For the former, it doesn't really matter, because DynamoDB Local ignores the throughput configuration. If we set it to `Infinity`, we don't throttle the requests so we can run more samples.

For the latter, I just want to leave some safety buffer so we don't run into provisioning issues. It is also closer to real word scenarios, where we provision the throughput higher than how much we would consume.
