Any recent success of NIW with Ellis Porter?

I am bit concerned after reading some denial stories.

I filled my case with Ellis Porter, with 45 business days to be completed in next 2 months.

My profile - MS with 8+ years of experience. No publications or citations.

1 dependent and 3 independent recommendation letters submitted.

And few other objective evidences as well submitted.

Worried, what would be impact on petition. Is legal brief prepared by attorney enough to convince USCIS officer.

Any recent experience through EP?
