I don't see CeeBee's point:
"it's not based on differences alone, so it can't work."

Sure it's based on differences, you have to fix
a range.
You can't know how good it works, since
we've not discussed the details yet. If my system just
weight's the result with 1 and the move-quality by an infinitesam amout, then
it's almost equal to the existing
system. These parameters have to be optimised.

If one player permanently looses by time, this will be
taken in account, I don't ignore the result.
But if one player permanently looses on time and played
well, he should get a better rating than a player
who permanently looses on time and playes poorly.
This reflects the expectation of his future perform:
he once might learn how to manage his time-problems.
It's just unreasonable to loose by time permanently,
there is nothing you can do, if someone wants to
outfox the system by playing well but then resigning
or loosing by time.. But that's unreasonable.
It's just rated as a bad move.


suppose there only multi-game matches, no tournaments.
System A only rates the outcome of a match,
which player won. System B also takes in account the
score, so a 10:0 gives more ELO-points than a 5.5:4.5 .
Which system would you prefer ?
