Nobody knows! You'll have to try it for yourself. It's much faster than what I've seen before, especially for 100% accuracy.
Here is a new version! It tries to save cpu as MUCH as possible. The "Cancel search" nodes are "hard coded" into it, but I will update this when I make it modifiable.
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
