computing average in nested loops

[buran]

@micseydel - they multiple by weight on the same line (12 or 2 in the different snippets they post) on which they take the input (num is actually respective weight). But of course you are right - they have weights in range (0-1) and sum of weights is 1, so there is no need to divide by 1. I was thinking to comment on this in the other thread but it slipped from my mind when posting an answer.

EDIT: I see your point now
