Hi all,

 I performed the test proposed by Franz

 Here I am not applying the mixing correction.


Generic MC: ratio(wS/rS) = 0.1709 +- 0.0024
DATA      : ratio(wS/rS) = 0.1786 +- 0.0056


Bch
Generic MC: ratio(wS/rS) = 0.1047 +- 0.0029
DATA      : ratio(wS/rS) = 0.1108 +- 0.0093


B0
Generic MC: ratio(wS/rS) = 0.3070 +- 0.0051
DATA      : ratio(wS/rS) = 0.3500 +- 0.0110


 Comments:

 - Total and Bch: data and MC are in good agreement
 - B0s show a small discrepancy but it should be stressed that:
   * the chid is higher on data and then the number of wS have to be up
     by a bit
   * the fit error is underestimated in this kind of high statistics fits
     because it does not take into account any fit systematics
     (comparable with the stat error here)

 Then my feeling is that the result of this check looks positive.
