Depending on how good or bad/tired I feel my blitz rating goes up and down between 1850 and 2100.
But that is nothing. It would be really worrying if my classical rating would jump quickly like that.
If you are talking about your blitz (or bullet) rating, then have no worries.
Besides that : imho in the end the chess content should count (no word joke intended), instead of the numbers of the ratings or the numbers of the game results.
I am actually sad that there's quite a few players who start to premove like crazy when they have 10 seconds left in a totally lost position while I still have 3 minutes.
A waste of time for both players.
Focus on chess content!
Try to play an immortal chess game!
Forget about rating and clock, and be creative and play for beauty, and create nice chess games to share with others, to inspire them.
