Not computer proved but I believe that it's true
There are other comps with different singles I suppose but in this 12-part
the only satisfactory one*  that I could find was in 5-6 at the half-lead.*
*I don't really think that the 'S' and the 'x' are different singles, one
simply occurs in an otherwise plain lead, the other in an otherwise bobbed
lead.*
