According to FFXICalc, you get 16.1 TP from 40 store TP(5 store TP traits + merits) from a one hit WS. So, you want to be at least 21 TP per hit(100-16.1=83.9. 83.9/4=20.975) to have a true 5 hit. To do that, you would need to TP in around 48 store TP after traits.
Note: I don't know if the math is right, I do tend to make mistakes, so if I did something wrong please say something xD
