I use system A,2,3 give +1points
4,5 +0,5 points
1/6 when x>=9 +1 x>=14 +2
2/6 when x>=12 +1 x>=16 +2
3/6 when x>=15 +1 x>=18 +2
4/6 when x>=18 +1 x>=20 +2
+1 odds are 54% +2 61% etc.
It was based on idea,that A,2,3 are very inconvinient cards for player
4,5 same ,but their power is not so huge
6 is little bit better for dealer ,but not worth to add some half point.And simulation proved it.
And of course it is better to count,we dont need any negative values.
Whats your opinion?
