Yeah.
So  so that was the other thing. And then we wanted to s just limit it to maybe uh something on the same order of dimensions as we use in a standard um front - end. So that would mean just doing the top I don't know ten or twelve or something of the KLT dimensions.
Yeah , and I think  and we sh again check  we should check with Stephane. My impression was that when we did that before that had very little  uh he didn't lose very much.
