Some random tech tidbits you may or may not already know. These aren't significantly helpful or useful, but knowing stuff never hurts.
1. High parry and low parry have separate timers. That is, a low parry attempt can be immediately 'canceled' into a high parry attempt (assuming it's off cooldown) and vice versa. Can you use this to option select common high-low mixups? Not really. Well, maybe you can, but I haven't figured out anything reliable yet besides Fukua's shadows. It does gives you a very wide window to parry assists, however, by alternating parry directions.
2. Beat Extend can be kara-canceled by doing
+ s.mk ~ lp or hp, compared to the other kara-cancel method of doing s.mk
punch button. (You can also kara backwards by doing s.lk instead of s.mk.) This is slightly faster than doing smk first. Whenever I try to do
smk ~ mp I get double snap instead, which is really obnoxious since that would be the most useful version to kara-cancel with this method.
3. Sound stun causes Sekhmet to freeze whatever she's doing for a time and allows Big Band to combo into throws. C.hp xx A-Train combos against her, including L A-Train. MK or HK Cymbal Clash into ground throw also combos against her. All of Big Band's other sound stun moves will freeze Sekhmet but leave Big Band vulnerable due to lengthy recovery.
4. Minimum distance HK E-Brake and MK E-Brake travel different distances despite taking the same amount of time to complete. This is completely irrelevant most of the time. If you know an extremely spacing sensitive setup, the difference in distance may be useful.
I know one, so it's handy for me, and in my case it turns the reset into a 50-50 against some characters with no difference in input except MK or HK E-Brake.
5. Big Band can dodge Double's car super with M Beat Extend, but it is very difficult to time correctly.
6. Microdash ~ smk xx HK A-Train reaches full screen. It grabs all characters who are neutral jumping at full screen, but if they are up-backing it will whiff. This is great for surprising Fukuas and Valentines who are sleepily upbacking and throwing projectiles.
