Looking in the app running against Bittrex and I see there is quite a lag between where it thinks the market is and what the real time market is like.  I figured there is going to be lag of some sorts, but I am seeing up to 10 minutes of difference between real time and the app. 

What is the expected average lag the app was built around?  Anyone else seeing this kind of delta? 

I did notice that it is not the same delta on all markets, but my best one is averaged at 5 minutes of difference.
