So basicly, like PRYCE said , if you want to risk the OH/Low mix up you will net around 31-33% meterless, the combo can be tricky, to get used to but its not execution heavy to be honest, Spending a Bar on TK will not net you extra damage, atleast on the live version atm... you will however steal resources from the opponent which honestly i still believe it to be of worth...
In the corner you can net 47% with a jump in 1 bar, doubt this will happen often but just something to keep in mind. however you can again go for OH/Low combo that will net you with 1 bar depending on your combo somewhere between 39 to 42% ending in normal push or Ex Push...
Im sure with the new frames in Push some stuff will be made much easier to execute compared to now... but i look optimistic at this damage and his new utilities
EDIT: speaking of Resource stealing, can someone plz confirm how much EX TK steals in terms of bar? because in Live its like 25% of one bar, i was hoping that in the beta this would be in the lines of 50%.. so if anyone can test that plz share
