Anyone Noticing Odd Results in Recent WT/OV Stats?

[Grrilla]

It seems that lately, there's been an unusually high occurence of discrepencies betwen WordTracker and Overture results. Most peculiar, has been the frequency of results where WT is showing a significantly higher number of searches for a term than Overture. Do you think WT is becoming a more popular search engine and a changing of the guard is occurring, or are the odd results merely system glitches?
