Even this is (perhaps) just poking numbers into holes.  Using the tool from the
above web site, I used the following:

Opponent rating was set to 2600
Total score to .01 (which is what an 1800 player would manage)
Your rating to 2600

and it spit back:
Your new rating is 2592, you lose 8.

Perhaps this calculator also does not perform FIDE type calculations.  Or
perhaps I am using it incorrectly.
