I will give the sub crawl a try, my partner already knows how goofy this hobby can be sometimes
Why -10 offset though, what's the pros and cons of that setting over the other -5, and -15. Going by the best I've learned about mixing levels, obviously movies standard is known quite well, TV programs and, I'm assuming TV series as well, are just 10db below movies. Music being unknown or varied, but I have heard mixers for music using 85db. Games is a mystery, I just always assumed they use a similar mix level to music as the volume of music to games usually seems similar.
