In this case it might act as an incentive. But it is not the purpose of a rating to provide incentives.
Why my rating fluctuates as waves of the sea?

“@SoupSailor72 that true, we all win some, and lose some. My point was that I continue gain and lose points, with what I called a "spikey", "sawtooth" waveform, recurrent. If we go back to the comment from @SriyogeshS , I think his opinion makes sense.”
It is possible that you are susceptible to tilting, I guess. Maybe try to take breaks.
The point I’m trying to make is that this is completely normal. There are no “biorithms” involved, no algorithm tricks, RD techniques, nothing. Just chess. Get better at chess, your rating goes up. Get worse, it goes down. There will always be fluctuation, that’s the human factor, and the luck factor. But don’t worry about it. 🙂

Glicko RD does not consider how fast you play. It considers you many games you have played (recently)
I believe you are correct. I forgot. I remember now having had this discussion with King Eric. But how many games you play is going to be relative to how fast you play and either way it's unfair, because it favors the person for a characteristic other than chess playing ability. Two years ago my rating was impacted by the "H" factor (Hospital) During my stay in the hospital my chess playing ability did not change, but my rating did. If I fell in Love (the L factor) I might concentrate less on chess and my rating would go down, but my chess ability (potential) would remain the same. The more you try to make the rating system accurate, the more inaccurate it will become, because it is intended in the first place to be an "estimate" of your playing strength. Estimates, by their very nature, are not accurate.
RD has nothing to do with how fast one plays. Each category of time, Daily, Rapid, Blitz, Bullet are completely separate ratings. The RD factor is about rapidly getting a person to their trueish rating. It does this in two ways, the amount of games played, and the amount of time between games. A new person has an unknown true rating. Wins and loses are large points with the Rd factor. A person which has not played for some time often gets rusty, and again the RD factor takes place in the same manner. If your true rating is 2000 and one would start with a zero rating and wins were 10 point each. After 100 wins in a row it would show as a rating of 1000, still 1000 points below your true rating. This what the RD factor is for and does. (Just numbers for concept) The Rd factor can get you from you starting point to your trueish rating of 2000, in 35 games instead of 200 games. It also works in reverse, when your rating is to high. The same applies when you have not played in awhile or for a very long time. At some point if you play steadily, the large Rd point gains will decrease as you zero in on your trueish actual rating.
As far as speed, while true one has the potential in a specific time frame to play more bullet games than longer games, that in itself is not the determining factor. Nor is there any favoritism in the rating system. The Rd and Glicko are simply mathematical formulas which have no favoritism built in. The two together have everything to do with how many games and the frequency of play, along with wins and loses and the point spread. It does not matter at all if I were to play 10 bullet games, 10 blitz games. or 10 ten minute rapid games, it is not about speed. If I were to play 1 bullet game the fastest, 1 ten minute game the longest, and 40 blitz games, then the most accurate rating should be the blitz game rating.
Because of the RD, there’s more pressure to score your first win right after taking a break.
