What part of what I said makes you think my internal information isn't from experience? Just to be clear; it is. I haven't described my specific experience, so claiming I said "it works perfectly for me" is not something I've claimed.
What you tried to say was I was claiming that since it worked for me it was therefore good. That isn't the case. I'm saying because it worked for me AND EVERYBODY ELSE, it's therefore good.
Ah, I had assumed that your internal information was from experience, either your own or your organisation's. Since that is not the case I am curious where your "internal information" comes from considering you completely disregarded @bsagdiyev's personal experience.
