Perhaps "weight" is not the best term to consider when thinking of the weighted voting system.

.

Instead, think of weight in terms of votes.

.

A signature member with the weight of 100 rates an image SEVEN.  They have just cast 100 signature votes of SEVEN for you image.   The standard rating is capped (today at 13) so they also have just voted 13 standard votes of SEVEN for your image.

.

Another signature member with the weight of 500 rates the same image an EIGHT.  You have another 500 votes of EIGHT in the signature rating total and 13 capped votes of EIGHT in the standard rating.

.

Finally, a non-signature member with the weight of 5 rates you image a 6.  This vote carries no standing in the signature voting as this voter has yet to achieve the signature (top 7.5%) level.  You would only receive 5 votes of six from this member in the standard competition.

.

Now, your image will be rated with 600 signature votes for an average of 7.833 [ (500 x 8)+(100 x 7) / 600 ]  (your image will have 2 raw signature votes)

.

Your image will also carry a standard rating of 7.2581  [ (13 x 8) + (13 x 7) + (5 x 6) / 31 ]  (your image will have 3 raw standard votes)

.

As you can see, all signature voters exert the same influence through their capped vote on the standard ratings while their full weight is leveraged in the Signature Rating Competition.  WE
