Topic: Tier ranges adjusted ...

Today I also adjusted the tier ranges. The key change is that I made the D-tier bigger by adding the range 30-39.

• Previously: D-tier ranged from 50-59
• Now: D-tier ranges from 40-59

I think this is more logical. It is the numerical middle-ground, so now it is basically 50 +- 10.

Now we have a simpler structure for all the ranges: F, E and D are 20 points wide, C, B, A and S are 10 points wide. This led me to adjust the voting algorithm which is based on tier groups:

• Previously: F and E formed the "low" tier group, D, C and B were the "middle" tier group, only A and S were the "high" group
• Now: F and E still form the "low" group, now only D and C are "middle", and B, A and S are the "high" group

This means that when computing the rating for a release, now B-tier votes count towards the "high" group, so they are regarded as more positive than they used to. Numerically this also makes sense:

• Previously: Low group: 0-49, middle group: 50-79, high group: 80-100 (50/30/20)
• Now: Low group: 0-39, middle group: 40-69, high group 70-100 (40-30-30)

So the new structure is a little more generous. What do you think?
