(This may be completely misleading)

Adding to adjacent bins amounts to a convolution in the F-domain,
which is equivalent to windowing in the T-domain. How this relates
to the problem at hand is a mystery to me ATM...

If you add two complex numbers, the argument of the sum will
be close the argument of the largest one if the magnitude
difference is significant  - just look at it as a sum of
vectors to see this.

Ciao,
