Steps to reproduce the problem:
There is no step to follow in order to reproduce the problem. It only concerns how site-engagement are defined in order to allow or block website using Flash

What is the expected behavior?
Every computer in the world should have the same engagement-score to be able (or not) to access a website built with Flash

What went wrong?
Every morning since the beginning of the month, I make some test on 12-13 computers concerning the behaviour of the site-engagement of Chrome to be able to know exactly how much "point" a user need to have in order to be able to run a Flash-website. 

My probleme is that 95% of my computers require 2 points of engagement while a single one computer needs 4 points.

We tested a lot around it but we don't find what could "create" the 2 more points required. 

Thank you !
