Jacky juggle

hi i'm a newbie here (and VF4!) and sorry if this has been posted before;

I'm just wondering whats the most damage that can be done after Jacky's f+K juggle? Lots of comp. videos show ppl choose to PPPP after the f+k.

Also, i'm not sure if P+K,P,K will execute a juggle? Lots of comp. ppl seem to able to combo into PPPP (again...) afterwards, is PPPP the best for juggle combos??

 

f+K - KPK or PPf+K generally do good damage
f+K - d+P - df+KK is good
f+K - dbPK is okay
f+K - PPf+PK is usefull against LW
f+K - PP - b+P+KPf+K is good against LW

 

after P+K, P, K you can keep juggling the opponent in version A (old) ...
the combo you see in movies is PP,u+P.

You can NOT do it in version B. The best you can follow with is u+P if the opponent lies still for it.

After f+K, probably the best guaranteed damage you will get against most opponents is P(G), P,P,f+K ... if they tech roll afterwards you might be able to punish them. If they don't tech roll, d/f+K (ground kick) will hit.
u+P might also hit.

If your opponent is lightweight, it is possible to do P,P,f+P,P,d+K.
If your opponent is heavy or you just want a very easy, damaging combo.. do f+K, P, u/b+K.
