Another point is, who decides whether a tab is complex? A beginner may find even the simplest Metallica songs complex and award complexity points accordingly. Maybe the best way to implement this would be to have a separate complexity rating system (from 15 in the current system) that would then act as a multiplier on the accuracy rating. I think that maybe this would be the easiest method of implementing extra points for difficult and complex tabs.
I like the idea of the rate of multiplication being psuedoexponential, ie, the multiplying factor increases by an increasing amount with each step up the complexity scale. As an example you could have the following complexity system and the relevant multiplying factors:
Complexity rating  multiplying factor (increase upon last multiplying factor)
1  1.00
2  1.10 (0.10)
3  1.25 (0.15)
4  1.75 (0.50)
5  3.00 (1.25)
Obviously, this has two main drawbacks:
1. To get these multiplying factors, Nomad would have to implement an exact formula which will yield all sorts of fiendish numbers as multipliers and this could lead to confusion on how the multiplying factor is calculated. Do most 1314 year olds even know what the exponential function is? However, I believe that a rounding system would nullify this problem.
2. You would still get beginners rating a song like No Remorse with a 4 or 5. This drawback is harder to eliminate without a moderator imposing his own opinion on the distribution of votes, ie, discounting higher complexity votes for obviously simple songs. However, I'd like to think that a realistic average would be attained if voting carries on as it has in the last week or so, even with the input of nonethewiser beginners.
