If there's a lower spread in the judges scores then it gives the public score more weighting than the judges, not less. To push it to the extreme, If all the judges ranking scores were either 1,000,001 or 1,000,000 but the public ranking scores were 10 to 1, the public scores would be far more important, even though the judges numbers were higher.
The best way to work out comparative weight of importance of two (or more) sets of marks producing a combined ranking is to take the standard deviation of each range of marks. The higher the standard deviation, the more "weight" the ranking scale has. Hence why people argue that Craig is the most influential judge, as his standard deviation is usually the highest.
