Hi,
As a house game, I recently played someone rated 947. I am rated 2179. I won the game, and gained 1 rating point!? I expected to gain nothing from that. Why should I gain anything at all, since I out-rate him by 1200 points? Is this an error/fault of the rating system?
Rating changes are always rounded up (if positive) or down (if negative). You gained a small fraction of a rating point, and that was rounded up to one point.
I was looking at that event
main.uschess.org/assets/msa_joom … 1-12630415
and I was wondering why the second highest rated player would be paired in round one against player 11 in a 13-player event (12 received the first round bye). Then I saw that players 5, 6, 8 and 9 all had first round half-point byes and thus the pairings (with an assumption that the wall chart supplement ratings resulted in the pre-tournament 1409 being 11 and the pre-tournament 1353 being 10) were a very reasonable:
1-7
2-10
3-11
4-13(unrated)
12-bye
I don’t remember another event where almost the entire middle skipped the first round.
You were being accomodating in giving a game to number 12.
This link, lansingchessclub.blogspot.com/20 … -rd-1.html, goes to the Round 1 results.
You deduced well that I was being accommodating by giving #12 a game - he and I rode 1 hour together (for a one game per week event) only to find he wasn’t going to play at all that night. So, I played on two boards at once.
That was gentlemanly of you to do that sir!
When I am directing I hate having players travel and then not play. I will try almost anything to get them a game.
What’s really fun is a 4-round 5-player event.
To avoid all the byes (if everybody agrees), you can set up the tables in a 5-pointed starfish arrangement and have everybody play two games at once. After just two of these double rounds, the round-robin is complete.

Maybe you were rated 2179.49, and gained 0.02 rating points to jump to 2179.51. Published ratings are rounded to the nearest whole point.

Nolan just corrected me. After the post-tournament rating is calculated, it is rounded up or down to a whole number. So next tournament’s pre-tournament rating will also be a whole number. WileCoyote’s explanation is correct.
