Very nice presentation!  I have just a few minor comments:
s2: for a short talk like this, IMO a table of contents is not necessary
S3: it would be nice to make the plot larger
s6: why isn't the BDT significantly better than the track multiplicity based tagger?
S9: I wasn't able to follow your explanation.  Can you clarify this?  I also can't read the plot labels
s12: "Uncertainties" would be a better title, since you list stat uncertainty

General comments:
-You should check with the relevant conveners to make sure it is okay to show your WIP plots (particularly those with data)

Regards,
John

 

Nice presentation, just one minor comment: 

On slide 3, the text and the plot overlap a bit. I would make the text smaller.
