Ten people answered the survey (I'm guessing the two who didn't are [@Hael] and Blackmist), and these are the results:

[hider=Diffierent Variations of 100]100 years, but split into four time skips of 25 years
100 years, but split into four time skips of 25 years

100 years, but split into two time skips of 50 years

100 years
100 years
100 years[/hider]

[hider=Different Variations of 200]200 years, but split into two time skips of 100 years
200 years[/hider]

[hider=300]300 years
300 years[/hider]

As can be seen, 60% want different variations of 100 while 40% want higher than that.
30% want 100 years
20% want 100 years split into four timeskips of 25
20% want 300 years
10% want 100 years split into two timeskips of 50
10% want 200 years
10% want 200 years split into two timeskips of 100

So, do we want mob rule or shall I work out some kind of average which attempts to be inclusive of minority votes?
