Dont know whats happened, last week I was doing 13 WU's per day, but one day this week did none, now only 3 or 4. Nothing has changed, weird. At this rate bpm will catch and pass me in a week or so.

The number of WUs have dropped considerably for you. Can you check whether the completed WUs are getting out to the stanford server?

I think you've about 20 days before I get to be No. 1.
