This skip is kind of new, I know I saw this tech used only once in the easiest skip by TwoPixel in his former World Record run in 3rd Patch, however, I have found different places that it can be used to save time.

Skip Explanation: In areas you are required to crawl, like in Backrooms 1 after the stairs, in water level going under the railing, and so on, if you crouch way before going under and un-crouch immediately after, right before you go under the object you are supposed to crawl under, then walk or run forward as you are un-crouching, you are able to skip crawling under the object, which saves time.

This skip can be done on all crawling sections in the run, except in Backrooms 2, trying will simply get you stuck in the ceiling.

This tech can be done in the water level, but for some reason it harshly depletes your stamina, making a harsh ending for the level making the run worse.

I will be making a video and linking it to this forum showing how these skips are performed shortly.

Places this can be used and their difficulty:

Backrooms 1:

Crawlway past the first set of tiny stairs: 2/10

Crawlway past the first crawlway, down the stairs: 9/10 Note: You need to keep momentum of crouch, and is required to un-crouch nearly perfectly before you go under the crawlway to do this one. This one barely works and glitches you through the wall if done properly.

Demonstration of both: Here

Road Level:

Very beginning of the level, difficulty varies based on how far right you do the skip: 4/10

Using both crawl skips in Backrooms 1 saves about a second, but is incredibly risky, and road level saves about a quarter a second. Using all 3 crawl skips can save you almost 1.5 seconds as apposed to not doing them, which in a run this short and this optimized, is a lot. These time saves are assuming you do them perfectly, meaning you do not waste time staying crouched, are always moving forward while crouching and un-crouching, and very quickly sprinting as you are un-crouching.
