Gah, you shoved about a million possibly good ideas into one tiny post. Let me see here...
So you're suggesting that we create seperate pages for each level. And on that page would be, first and foremost, a number of good strats for different times, ranging from WR to just ok, for each of the difficulties. After that could come some commentary from best players at the level, maybe thoughs on how difficult it would be to tie/break the WR. Another neat feature would be a listing of comprehensive Target Times for various places throughout the level.
It's a good idea, and it would certainly give a home to such pages as YE's Ode to Defection and ST's Ode to Frigate. But it would also take alot of work to do it, and do it right. Maybe we would be better off just getting quality WR walkthroughs created for every level.
The graph thing is kind of interesting, but I'm not sure it'd be worth the work. We'd be doing something like finding out how long it took everyone to get their WRs, and then people could look and find the easiest ones? Eh, I don't know about that.
As far as my graphs, I just want to point out that the points one is a few months behind, time I've stopped updating, and total time I'm still tracking, but I need to rework the graph to go lower.
And then, for videos, keep your dirty hands off that idea, YE. For another month at least.
