I recently designed a ship that reaches the shattered planet at 1000km/s , i posted it on youtube and reedit, it got a lot of attention (22k and 170k views respectively), i also saw at least 3 people trying to make high speed space ships to reach it. In both places i posted the achievement, i mentioned that i wanted to create a speed running leaderboard for this type of achievement, i and i received a lot of suggestions for it, here's how i would implement it:

How to measure time:

The timer starts from Nauvis (or it could start from the solar system edge) and ends when you reach the shattered planet. The final time would have to measured using In game-time (that is, considering the game always run at 60UPS), however i don't have a solid idea on how to do that, since there's no mod or setting that counts the IGT (that i am aware of), my best idea is to add a small physical decider combinator in all ships competing in this category that acts as a clock, counting the ticks from start to finish. Although I'm not sure how reliable that would be moderation wise.

Rules:

-You must not bring anything on the ship, this means, if anything takes damage or breaks, it will stay that way. Making a ship that goes fast, then breaks, then stops, then gets repaired, then repeat, is not fun.

-You must include a blueprint string of you ship in your submission (with factorio bin).

-The ship must be theoretically build-able on vanilla space age (w/quality), without any modded or cheated buildings (e.g infinity accumulator).

-You can use the editor mode to build, test, record and do the final run, as long as you don't interact with the ship in that last one.

-Your ship can be "warmed up" before starting the run, that means, full of asteroids, fuel on the thrusters and ammo on the belts, however you must not abuse this rule by adding massive buffer of finished goods (e.g massive belt buffer/storage of ammo).

This is because most ships in this scale are designed to have hundreds of asteroids of input/sec, and quick starting them for the first time (until it can go at full-speed) can normally take hours.

-You must include a video of the entire trip that clearly shows the ship working (zoomed in), it can be a time-lapse.And in the end, you must prove you don't have any cheated buildings in your ship and show off your infinite tech levels.

I am not sure if that is a good rule, since while it would simplify moderation on the category, it would definitely raise the bar for entry, since not everybody has the storage, time or will to make a multiple hour video of their ship flying. Alternatively, the moderation could be done by manually testing if the blueprint attached can reach the shattered planet.

Adding a cap to infinite technology

This is the biggest variable to decide on. If we don't impose a cap in infinite technology, any ship with a single gun turret could reach the shattered planet with a high enough tech level (since I'm allowing building and testing in the editor), i received a lot of suggestions on this problem, many agreed that there must be a tech cap. One guy suggested a "infinite technology level point system", in witch you would spend a limited amount of "points/ levels" to research infinite techs, like a RPG.

In my opinion, the technology cap should be based on what levels of tech are achievable in different sizes of factory, this would need to be agreed on by the community,but i am thinking:

in number of science packs used for the last level of each relevant infinite research (the stronger explosives tech should be double the others tough, since its the most important): Small space age base: 200k science requirement max, Medium space age base (in my opinion this should be the most competed category)1M science requirement max, Mega-base, 1 billion science requirement max, Uncapped science level category, No infinite researches category.

Obviously these are just suggestions, there is no need to add categories for each of them.

This isn't a "real speedrun", but it should be added

If you consider a speedrun, a raw measure of player skill/swiftness, this isn't it. This category would be more of a Shattered planet ship designs leaderboard than an speedrun, but i don't think that designing such a ship would be less impressive than a speedrunning world record. If there's one speedrunning community that would embrace this "less raw player speed, and more of smart designing" leaderboard, it's definitely this one, since it would fit in with the 'iterating on designs" aspect of the factorio community.

And yes, i think a speedrun.com leaderboard is essential for this specific "category", just so any factorio player can quickly answer (without depending on unreliable internet searches) the question that we all had at some point: How fast can you travel to the shattered planet?
