Surrender number: Surrender if the count per deck equals or exceeds the number, do not surrender if the count per deck is less than the number.


My understanding of a "reverse index" is when you do apply the decision "the other way". For Surrender, you do not surrender at or above the index (like explained by Wong) but only if the count per deck is less than the index.

What you're saying is that the basic strategy calls for Standing 17 vs 10 BUT that there's a reverse index at +13, the point where you would not stand anymore but surrender. This is not a reverse index, this is simply the point where the surrender index kicks in. If surrender isn't offer, you would not do anything other than standing.
You are right, it is clear that my understanding was too far-fetched, being something simpler to see. Thanks for the clarification.
