Here are a couple of tips for how to decide whether a map is worth running in All Border%:

• Before making your first input, look at what you can see. If you can see any map edges you can judge whether you're close to two edges - if you spawn in the middle of the map, that's an instant restart. If you can see the center of the map, and it doesn't have a relatively flat path from one corner to the other, that's an instant restart.

• For the current wr (40s), you want to be at the first corner before 10s. If you hit it later, you might as well restart. The theoretical best is 7.542s (when you spawn 32 blocks from both edges), but I've yet to see any run below 8s. The theoretical best for corner-to-corner is 30.170s.

• When moving, you want to be as close to the diagonal as possible. Walking sideways loses you time, so it might be worth it to destroy blocks in your way instead of walking around them.

• Water can be traversed if it's 1 deep by looking straight down and spamming build and jump. Practice this a bit, as it can save a god run if you're lucky.

Other than that, it's just a matter of spamming new worlds and hoping for the best. The faster you give up on a bad run, the more worlds you'll get to try.
