So. Which means that  actually the weight on the well - matched is  Well I well what what  What happened is that if you have a small improvement or a small if on the well - matched case  it will have uh huge influence on the improvement compared to the reference because the reference system is  is  is quite good for  for the well - ma well - matched case also.
So it  it weights the improvement on the well - matched case really heavily compared to the improvement on the other cases ?
No , but it 's the weighting of the  of the improvement not of the error rate.
Yeah. Yeah , and it 's hard to improve on the  on the best case , cuz it 's already so good , right ?
