[Computer-go] Informal study

Just for fun I just took a snapshot of the main page and the bayeselo page
and I'm comparing the ELO ratings on each page for a few active programs
near the top:
*Program BayesElo Incremental*
*------------------ -------- ------------*
*MyGo1.0_np 2775 2672 (not active)*
*Valkyria3.5.16_4cx 2723 2625*
*Fuego-1166-8c 2722 2601*
*ToGo-207_1c_b 2558 2484*
*Valkyria3.5.9_P4Bx 2560 2448*
*iced_goanna 2295 2199*
*N11_L3Chkif3.3 2248 2147*
We should, over time, see these gradually converge. Note that we are
approximately 100 ELO off in every case.
I have lazy,0 and lazy,1 playing, but not simultaneously. From time to
time I am synchronizing their ratings with bayeselo. I also noticed when
doing this that their ratings jumped. So these 2 programs will be feeding
the ELO economy with inflation points to bring it up to the bayeselo
This will probably take a long time - but I don't view that as a bad thing.
I'm not even sure this additional program will do the job because the
anchor by itself was not strong enough to prevent this deflation. The one
active anchor probably prevents it from drifting more than 100 ELO.
It occurred to me that I could also copy over the bayeselo ratings of
players who have played less than N games, with the understanding that
their ratings with few games are pretty unreliable and their performance
ratings (as measured by bayeselo) are more reliable.
