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.
Right.
By just taking the top whatever ?
