Alrighty, assuming the schizo have the same forward pressure adjustment as the jesters. The little screw at the bottom back of the heelpiece (not the DIN screw inside the "dildo"!!!) is the forward pressure indicator. Turn that screw one "click" clockwise (you'll understand what I mean by click when you turn it). And you should se the heelpiece move ever so slightly forward. One click should be enough to account for 1mm difference in BSL.
The forward pressure scre on the jesters is here:

If it ain't there, I can't help you finding it. But 1mm is barely nothing, so unless you have problem with unwanted binding release skiing them, it's probably fine.
PS! To any other readers of this, screwing with the forward pressure without knowing what you're doing is not advised. This here is how to account for 1mm BSL difference on a binding set correctly for the 1mm bigger bsl.
