Benchmarks are the worst, except of course for the alternatives.

The present Boinc run benchmarks are too unrepresentative across
different hardware to work well enough even within a project. Hence the
dire inaccuracies when trying to award credit using run time.

Rank is rather hopeless as a metric. I dedicate 1% of computing power to
some projects and I am in the top few. On others I dedicate 33% of
computing power and I am not in the top thousand.
If you want to get into the top few
Hey! An excellent thoughtful thread! And the answer is...? ...

If you really want to open that can of worms, how about the fact that a
floating point add (which is a floating point operation) is dramatically
easier than a floating point cos().
... and the fact that an AMD processor might do adds dramatically faster
than an Intel, but do cos() slower.

Solution: Give up on cross-project credit parity. It's an impossible
goal.
with boinc credits the simple rule is there's no pleasing anyone. I actually
think that if my GPU does 10 times the work of a CPU that I should get 10 times
the credit (which I think is what you or the noisier credit people are
complaining about)? at the very least, that promotes better
If your computer does 10 times the work per hour than mine, it should be
granted 10 times the credit per hour. However, that works out to the same
credit per task for both computers as yours will go through 10 in the same
mine will go through 1.
Some people believe that the faster computer
