Another thing is that don't know which of your script only works on videos on live, or static videos as well?
Actually, all of my scripts are mostly cost less than 100KB each for memory, and the additional CPU cost of the duplicate code might be microseconds level.
I know many scripts would mess up the script manager's list though...🙃
My scripts starting with "YouTube Live" would work only on live streamings.
The only exception is "YouTube Click To Play" which starts streaming videos on load with intent.

Don't know if you can just reduce the redundancy in all of your scripts and create one pack of performance boosting script... lol
Too lazy to check out every one of them... :P
