Between single-digits 1 and 2, both are interrupted each other.
[if r8c4=1] cause [r1c8 must be 1 and/or 2] => contradiction.
Thus [r8c4<>1], instead [r8c6=1] then stte.

2. Your single digit chart doesn't show a 2 at r1c4, and
3. I don't understand how you're using the charts.
A: digit 2 B: if r8c4 = 1 C: r2c6 is 1 single
r1c4,r2c7 eliminated therefore r2c4 is 2 single
