Development length of your horizontal bars is critical
if it is a shear wall. However, the top bar factor was never intended to
apply for walls.

factor is also sometimes called the "top bar factor". Basically,
it accounts for the fact that in deep members, you are likely to get
some settlement (resulting in small voids) below the bars and the bond between
the bar and concrete may not be as strong as if there was no settlement.
It does not apply to vertical bars. I suppose it applies to
horizontal bars in walls but development length is not critical in most walls.
