Only rated blitz here on chess.com should affect the blitz ratings RD. Unrated blitz here should not count.
The OP seems to be a bit "rating horny". Winning or losing 100 rating points in one blitz session could happen even with a low RD.
Suggestion to Improve Rating Stability
Sort:
@notmtwain - I'm not really making any effort to game my rating here on chess.com so your graph isn't relevant. To answer your question I should be rated between 1600-1650. Those few rated games you see on my chart were accidents. The Android app can be sneaky and sometimes I accidently play rated games that I didn't intend to.
FYI - I did try gaming the rating on FICS (which also uses Glicko) and managed to bump it to about 1750 before I lost interest. My USCF is floored at 1700 and is currenly 1902 (1729 Quick). My FIDE rating is 2054. I have not played active tournaments since January 2013. I'll leave you to decide if my current chess.com rating is accurate or not.
@SmyslovFan - I'm not "upset" with Gliko. As a rating formula it has it's strengths and weaknesses. I just believe Gliko can be manipulated by altering the number and frequency of rated games played.
IMO - Gliko actually discourages rated tournament play by those people who wish to manipulate their rating.
"Those few rated games you see on my chart were accidents"??
You have more than 2,000 rated games.
