Felt like this deserves a new thread, though its similar to the other thread I made.
It's possible to void yourself out anywhere on the plateau, which will spawn you outside of the shrine of resurrection. This includes inside the shrine of resurrection and the tower before you're supposed to be able to.
Have a save file in the cryonis trial. On a clean save, the shrine of resurrection should autosave right away. Load into the cryonis save, create a pillar in the water and climb down it and open the inventory on the same frame. Then from the inventory load that autosave.
From there it'll void you out, and you'll spawn out of the shrine without the slate. Of course this'd be considered ng+ though.
Based on the minor testing I've done, it could save 20 to 30 seconds, though instead of warping to shrine of resurrection after bombs (you can't warp if you do this), you'll have to void yourself out again.
This seems useful for longer runs, like 120 Shrines and 100%. Can you post a video of these finds? I'm sure people would use them if you posted a youtube link.
No videos, don't have the ability to record, except from my phone which won't be a good quality recording. Neither of them right now save a lot of time, and couldn't be used anyways since theyd both need a save in cryonis beforehand, unfortunately.
Small thing I noticed when testing this out. It seems that since you avoid all opening cutscenes, time doesn't ever start, so (at least for me) its forever 5:15 am...
