There is some creative engineering going here :) have a look:

I'm not sure why you think that's creative engineering. What you're pointing to is the depth of available configuration that the contributors to TSBS have exposed for each database. It's totally open source and anyone is welcome to add more configuration and options! I believe (although not totally sure) that Altinity and ClickHouse folks added their code a few years ago - at least it wasn't anyone on the Timescale team.
That said, we didn't actually use those scripts to run our tests. Please join us next Wednesday (10AM ET/4PM CET) to see how we set the databases up and ran the benchmarks. We'd be delighted to have you try it on your own too!
