I have installed the private instance and i am able to run the tests using a web browser. For ex:
1) I open

2) Enter the URL to be tested and then click on submit. I see some test results

3) Now i execute(Have the node wrapper installed):
#webpatetest test -s > testresults.txt

4) Fetch the JSON URL from test results, parse it and fetch the FirstByte, Loadtime, FullyLoaded time etc.

5) The test results vary by approximately 2 Seconds when compared to the test results generated on a browser in step 2 above. I fetch the median values from the JSON.

Why is there a significant difference in test results? Am i missing on some thing.
Had to recheck my settings. I have confidence in the consistent metrics now.
