In the new Army promotion system, is attaining an SLC slot an indicator of being selected?

After much research, I've come to find no information that suggest SLC notification is an indication of selection. I have also come to find that T.E.S.P (in my opinion) would work a lot better than S.T.E.P.

Truth be told, Schools Branch has no access to promo lists. Slots are given based on availability to those who have mat the prerequisites to attend. Does it look like it might be a good sign? SURE! Is it? No analysis has proven such a thing.

My understanding is that usually the top 10% are offered the seats first, but that is not a guarantee of promotion.
