Take into consideration the second run, since the difficulty is shown in the first run. Since the second run I did the vs Ryo, but I saw that the same run is equivalent to the 2 category level 1 and vs Ryo.

MOD: I slow-motion'd the final blow on Ryo and it seems that when the kooken sprite changes to its "blowing state" (a blue circle), the time is actually 16:00.86. Also Ryo got into his pain state on 16:00.93, so I corrected the time to 16:00.
