Richard-
The calculation actually works in the opposite
direction to tht expected,
but
your assertion is false. 549/180 != 548/179 Not voting for an entry
increases its average.
Nonsense. Not voting on an entry has no impact whatsoever on its average.
A logo with only 1 voter who assigns a score of 1 has the lowest score
even if all other logos are voted on by 10000 people. The numbers 548 and
549 above are arbitrary. New voters can increase or decrease the average
by assigning a value on a scale from 1 to 5.
E.g.
3 + 4 + 2 + 1 / 4 = 2.5
3 + 4 + 2 + 1 + 5 / 5 = 3 - new voter increased total
Whereas not voting on the logo does not affect the average at all.
