I managed to get my rocket defense built and started the landing sequence in just under 8 hours (7:59). The landing takes 10 minutes, so that puts it at about 8:09 for the victory screen. My first speed run attempt took 15 hours, so this was a great improvement. I stopped researching at the end to focus more resources in to circuits, but my pollution was over 25k for a while.

Did you really use the standard settings? No peaceful mode, no bigger ressource fields?

If yes: Wow, that's pretty fast!

I didn't change any setting. I did make sure I had a good starting location since I was doing a speed run. I was worried about coal until I found that gigantic field to the south.

I probably could have started module production a little earlier to save some time and resources. Productivity modules can really cut back how many alien artifacts you need to gather. I still need to work on my circuit production layout as a single pipe develops bottlenecks even with fast belts.

A Dual belt mainline is almost as simple as a single belt mainline. (copper/iron on separate belts, instead of being combined.)
Combating further bottlenecks by having a new assembly for each machine that needs a component made can be useful. (though somewhat expensive early on.)
The real art/science comes to getting the resources *evenly* distributed to the branches if you go for a non-linear setup.
