How fast is Mach 229 224.5 you ask? Well, an aircraft broke the sound barrier at speed exceeds mach 1. Youmu can move at least 70 times the speed of sounds. In single slash. And that's quite fast.
She is saying it takes 1/30 of a second to make 2600Km, meaning that she makes 78000Km in a second. Comparing this to the speed of light its arround 1/4 of its speed.

Uhm i dont know how did you came to this conclusion, each match means its 1 time the speed of sound... meaning 229k match its 229k times the speed of sound.
All the cool kids were doing calculations, so here's my take: According to Wiki the yojana varies from 6 km to 16 km, and it's safe to assume that, if Gensokyo were present on Earth, it's air temperature would lie between extremes that we have measured. So, if Youmu travels 200 yojana in 1/30 of a second...
At her slowest (traveling 6km yojanas in Al'Aziziyah, Libya) Youmu travels at Mach 98718.58. At her fastest (traveling 16km yojanas at the Vostok Station, Antarctica) Youmu travels at Mach 353100.85.
If, however, we assume Youmu's calculations are correct, we know her speed (78000 km/s) and Mach number (27000) which implies a speed-of-sound of 2888.89 m/s, which would require an air temperature of over 4000 degrees Celsius... Or, for all sound to be transmitted by Aya.
PSB said: seems like they counted it as a motion required 1/60th of a second rather than 1/30th.
Well, 60 FPS is the speed Touhou games are meant to run at, thus, two frames would be 1/30th of a second. Now we can safely calculate the speeds of all other movements in Touhou!
You've got that spellcard, "200 yojana in a flash", right?
Ancient Indian measure of distance. See wikipedia.2808×10^5km/h .... that's ... roughly 27000 Mach.
2808×10^5km/h is actually approximately Mach 229000 in Earth's atmosphere. But then again, we're talking about Gensoukyou here...Yes.What speed does that compute into, I wonder?Hey, Youmu~~Ah, yes, Yuyuko-sama.It's not time for lunch yet, you know?Um, one yojana is roughly 13km; the motion takes 2 frames, so that's 1/30 sec; hence the speed is...Now that you mention it, I've never actually calculated it before.What's that?It's a kind of abacus, called "calculator".Ho... I wonder if that's for real?Shall we perform actual measurements after lunch?*heart pounding*At that time, no one could have predicted that this would become the beginning of it all.Let's get this show on the road!
