I'm getting extremely close to the point where I don't want to do daily races, anymore. I did 1 race, today (just now). I was DR "C". I started 16, finished 12th; and had a clean race. My DR dropped over 2000 points. And that dropped me down to the level below.
WTF?!
The whole finishing ahead of drivers who have a higher DR rating than you, the door numbers, all that BS needs to either go away, or they need to ALSO take into account what kind of race you had. No penalties? Your DR goes up a bit. Clean race? Your DR goes up a bit. Make clean passes and finish higher than where you started? Your DR goes up a bit.
Now I'll be in a lobbies full of rammers, punters, and overall idiot drivers.
🤬🤬🤬
ETA: Yep, I think I'm done. Just ran another race. Started 15th, finished 10th; and another clean race. DR dropped another 162 points.
The DR system is basically broken under 40K DR. It all depends too much on who you are matched with and DR is no indication of pace at lower levels. Too many new account entering all the time (rooms full of E/B are very common) as well as DR resets all the time. So even if you get matched with all C/S, quite a few are probably racing with DR.A pace or even higher.
I don't qualify and what happens to my DR depends on time of day, day of the week, how dirty the backfield is, who I'm matched with and lastly how well I perform...
How dirty or clean a race is also has little to do with DR and SR. Time of day is a much bigger factor and of course whether you're in the backfield or front.
DR calculation is just some formula comparing you to the DR of others that entered the race. Since DR isn't really tied to race pace (only at the very top you could say it is) it's basically pot luck what happens to your DR.
Best you can do, ignore DR.
What I hope GT7 will do is overhaul matchmaking entirely. Leave DR out of matchmaking completely. Instead determine race pace for every track/car combo and make matches based on that.
Race pace for a certain combo can be refined while doing that combo, simply by taking the average of your lap times minus outliers. Take this from the last 5 (or more) times you did that combo and you have an accurate running average. Much better than one DR number that takes many many races before it resembles your pace in a certain combo.
To determine your pace for the first few races, either take a modified (lowered) avg from your best qualifying laps (minus outliers). Race pace is usually lower than qualifying pace but since it's a fairly consistent difference the system could easily take that into account. For example start race pace is 95% of your qualifying pace.
For those that don't qualify, either base it on past experience on that track (modified for the current car / tires combo) or use some prediction algorithm based on your other races and track experience for the this track.
PD has tons and tons of data. They need to hire a statistician and together with an AI specialist it should be possible to make a predictive algorithm to sort everyone on actual race pace.
DR can still remain separate as some overall combined score. But get rid of the resets and let it not have any influence on matchmaking. Matchmaking should go by SR, then sort everyone on race pace to make rooms. (While fixing the bug that the fastest lower SR players get added to the slowest higher SR players)
No more easier races by dropping SR.
No more sandbagging possible (unless you intentionally drive slow for 5 races)
No more getting put with too high competition on tracks you don't really have experience on.
This way GT7 can deliver what GT Sport promised. Matchmaking that puts you together with people with similar driving style and race pace. (If SR gets fixed as well, that's another story)
