If BW thought that then surely they should not only pay for 2020 clip now but also pay some advance on 2021 !! That would make the decision easier.Wrong again.
You are not comparing like with like.
We don't know what this years auction price is or what the handling costs are.
Until the last year BW returns have been better than the others.
I admit you need a crystal ball to know what will happen in the next 12 months but as I said the odds on prices getting better are good.
