Do colleges use the collegeboard SAT converter or is that a myth?

I tried finding the answer to this by searching the forum, but couldn’t find.
I heard from some people (friends, alumni, etc) that some colleges that I’m applying to (Amherst, Vandy, Emory, Ivies, etc) are NOT using the college board converter to convert new SAT score to old because it is “too harsh” and “does not represent the exact conversion”… of course, this can be wrong.

I was wondering if anyone could support/refute this? I know many of you may not know, but does it sound logical?
As you may know based on my old posts, I got a 1510 new SAT, which converts to a 1470/1600 old SAT. Although this is a decent score, it really is the make it/break it on Naviance (ik I shouldn’t depend on it). Based on scattergrams, for Amherst (for example),almost everyone in my school in the range of my GPA and 1510 SAT got accepted. But if you convert it to a 1470 with my GPA, it’s very mixed with rejections and a few acceptances… Thoughts?

Please don’t be too mean in the comments, I’m just asking

I don’t think anyone knows, but there is lots of speculation in a thread called “Old SAT scores compared to redesigned SAT scores”. Not sure how to link to it.

OP Naviance added points to the old SAT Math+CR according to concordance. So if you looking at Naviance under the 1600 tab and you see that all scores of 1500 and up where accepted then you should be fine. Those 1500s that you see are actually 14somethings in the old SAT + the concordance. You do not need to subtract points from your score because the old SAT you see is inflated.
