- 2.42 (SoD Light) xlsx...
I suggest we write here how long it takes to open the 2.x physics engine on your machines, and with which program, on what hardware. For example, an early version of Foxit Reader is very fast, but also very buggy, while Adobe itself weighs as much as an operating system...

2.42 (SoD Light) xlsx didn't open properly at all, even though I installed the necessary converter. I removed it and kept one of the 2.0 - 2.2 versions (I didn't delete 1.16). 2.43 in PDF opens in Foxit Reader in 4-5 seconds, and then 2 seconds for subsequent openings.
I think it's a good idea to keep the main game information and move the extra stuff to an appendix.
