What’s the link for your info?
This is where I got mine:
https://www.southernstates.com/docs/eq/0610_horsefeedvalues.pdf
It says the NSC is 29%, with the starch + ESC being the 21.9% from your list. Arguably, the accepted definition of NSC is starch + WSC. It’s those water-soluble sugars which leach out when you soak hay to reduce the NSC.
It was emailed to me from Ruth ,Feed Division Technical Service Southern States Cooperative
as the current NSC List for 2017. I get a new list every year emailed. Contacted them to find out why the different list vs. what was on the website. Interesting.
As per the feed division via email.
"The chart online is outdated. Use the attached chart. We use NSC = Starch + ESC or simple sugars because these are the only two values that cause a glycemic response or rise in blood sugar and insulin. WSC includes ESC and fructan sugars, which aren’t absorbed in the small intestine.
Fructan sugar content is low to absent in grain products and only of significance in cool season grasses."
So they no longer measure the WSC for grain and use the ESC + Starch.
“arguably” LOL
Dairy One and Equi-Analytical use WSC + starch. All the info on safergrass is about WSC, not ESC. All the scholar articles on NSC that I found, to try to support the SS perspective, use WSC and not ESC as well.
There are cases where ESC has to be taken into account for some horses, as a feedstuff that should be low enough NSC (WSC + starch) causes problems, and the theory is the ESC might be too high for them.
So given all that I think I would be inclined to avoid this particular product. Clearly some testing came up with 8.3% WSC for this product, and I don’t think that can be ignored.
LOL. I also have been emailing Ruth. 
Today she sent me an email about calories from oil v. omega plus. I just replied, saying that I was told to feed 4 cups of Omega Plus and I wanted to know how the NSC of that much Omega compared to the NSC of 2 cups of vegetable oil. Calories are not that important. If a thin horse gains weight, he is getting the amount of calories he needs.
Ruth is a busy lady.
I printed the chart out and I agree that, until a new chart is posted, I will use the current chart, since it uses the standard components.
Oil is 100% fat - no carbs, no sugars.
Is there a reason you can’t feed a straight fat supplement in powder form? I can’t get my horse to reliably eat the powdered fat supplements, but a lot of people like Cool Calories and I really liked the HorseTech FB100. Those both should have no carbs/sugars. And there’s Buckeye Ultimate Finish 100.
