Amok,
I don't know the answer to your question (especially since I barely survived intro trig in college.

). However, I'd like to at least voice my opinion here (and soon to the good folks at D.Net) that a percentage done indicator of some type would sure be nice.
I know that they have expressed the fact that without knowing exactly how many nodes will have to be computed for each stub (which is impossible) there's no way to
truly guage the % done of the project, but even if we only saw a % of completed stubs vs. total stubs it would sure go a long way towards making me feel the progress of the contest in a tangible way.
Would anyone else like to see this done? Does anyone know of any technical hurdles that would preclude this?
