From the produced run13 period one data, we have roughly reconstructed the Ws (very preliminary).  But the efficiency of finding W should be not changed significant
Based on the W efficiency, number of golden Ws from per pb^-1, the W yields for run13 and run 2020 long range plan were estimated.  

1. The uncertainties of W AL are estimated accroding the formular, \delta AL = 1/(P\beta\sqrt{N}), where N is the yield used for the AL calculation, \beta is the background delution and P is the average beam polarization. 
2. The central values are from the DSSV08 estimation, the blue curves.
3. The first and last bins are for the FGT, which was provided by Bernd.
4. The delivered luminosity was implemented as Elke's suggestion, and also Elke provided the numbers.
