From my understanding, speedrunners usually start, stop and split timers manually. If that's the case, wouldn't it be really imprecise, considering speedruns often come down to less than a second of difference? It would make sense if they had a program to start it on first input, do rough, imprecise split times manually, and went back and edited it to end on the exact right frame in post, but I also know that speedruns are often livestremed, so what am I missing?

I want to build a Terra, Magical Adept deck, and I was looking online for some ideas, but noticed that pretty much everyone does her with the summoning cards from the final fantasy set, or at least with sagas. Does she work as the commander for a not strictly saga commander deck or am I missing something?
