They've been posted before but it's still useful. Deep jumpkick combos only work consistently on the right side corner. Only 2 of these combos really increase the BnB damage:
jip 212 freeze, deep jumpkick, 224 slide = 36% compared to the normal 33%
jip 224 freeze, deep jumpkick, 21, 222 = 37% compared to the normal 33%
