For what I've seen recently the better ways to get safe Okizeme with Terumi are like this:
Midscreen: After 22C lvl 3, do 66 2D. With the distance you have from your opponent, you have time to think to go for Oki or bait DPs.
Corner: After 236D or 6D(needs a back dash after touching the ground, depending on the oppponent you could want to walk back a little after 236D), do 5D > 2D for the same advantages the of the first one. For this option watch out for counter attacks: Hakumen, Litchi, Tager, Jin and Terumi.
In this moment I can't play, so anyone could tell the data of the next combos? Both are Midscreen:
1) 5B > 5C > 2C > 5D > 236D RC (3) > 66 2C > 5C > 3C > 22C lvl 3
2) 5B > 5C > 2C > 6C RC (3) > 66 2C > 5C > 3C > 22C lvl 3
