idle speed smooth running control

After cleaning my injectors via the direct method in the howto's my idle speed smooth running control in vag says I now have these readings:

#1 ---- + .9 to .12
#2 ---- -.59
#3 ---- +.19
#4 ---- + .21 to .24

I am concerned with #2 reading a negative number. Should I be? I know it's realitive but that seems like it should be a + number not - number.

My previous numbers before cleaning were:

#1 ---- -.04
#2 ---- -.07
#3 ---- +.28
#4 ---- -.05

Seems odd to me. I think I need help understanding this.

Thanks
Pete

got, correct me if I am wrong, but the spec reads:

+/- 2.0

I think the numbers were better before cleaning.
