No, it wasn't. That was a subordinate clause in my overall statement that I disagreed with the premise that 75% of businesses would migrate to Windows 10 in under 2 years. . . You said they would. Now you are parsing your statement, as you have tried to do in the past.
Go back and look at my first reply to you. I quoted that, and only that statement as the part I took exception to.
You said yourself they don't provide any details about their survey methodology, so we don't know exactly what "penetration" amounts to.
I quoted from the article that they say they found a 60% "penetration rate" for W7 two years after release, so that's not a prediction but a measurement from historical data. It doesn't explain the methodology but it's at least data that can be extrapolated from to evaluate their prediction, and that's what I did.
We don't know exactly what the methodology and metrics are for what they're calling "penetration rate", but we know even less about whatever it is that you're using that says it's "bogus".
