I've never personally seen nor have any other SAMs I know of reported getting more than 1-2 TP return from a WS, even though in theory a Zanshin proc with Ikishoten merited should give at least 4-5 TP. But it's impossible to know if that's evidence or not as no one really knows whether Ikishoten would work on a Zanshin swing in a WS. Seems like it doesn't.
Only way to really tell is to WS a bunch of times on SAM with an assload of Zanshin and absolutely no form of DA, and see if you get any low TP returns.
