Hah! I just tried it, all the way through the file, and it took me
3568.429881811142 seconds, i.e. all of an hour bar 32 seconds.
My machine is no way slow, being a first generation AMD Ryzen from 2017.

Other than what I told you last post (lack of braces), not yet, but I'm
going to take the first tenth of the OP's file (which is 4 Mb) for
testing on.
