I wouldn't call it a hogwash. It's a different perspective than yours.
IMHO, Ron was not as detailed as you were in your calculations. I'm sure Ron acknowledges the SOFAD, I have seen his earlier posts. But, in this instance, he was specifically referring to EB3->Eb2 upgrades as being the single reason for EB2 dates not progressing these days. Which, I think is correct. SOFAD will not come into effect until July anyways, it's too early to talk about it now(from his perspective)?
Also, we must know that his articles doesn't have to be as detailed and are geared mostly towards lesser(EB immigration)educated. The way I look at it as a Math grad student, commenting on a primary school math teacher on his tutoring techniques.
No offense implied. Just, expressing my view here. ( No, Ron is not paying me for this

) Sorry for digressing the thread, this will be my last post on this particular Ron's matter.
