Even for a 500 rating point difference, the weaker side should get 24% of the
points.  If we simplify the math by ignoring draws, four games in a row would be
.24^4=.0033 (or .33%  or 3.3 times out of 1000 four game matches).  So I am
still not sure 4 wins in a row for a 500 rating point difference should cause
shock.
