Proposals for DG-EDGE Consideration

Proposal: Drop Worst 5% of Events from Combined Average Delta Calculation

Hey everyone,

I wanted to start a discussion around something that I think could make our average delta stats more accurate and more representative of our actual pace as drivers.

Currently, DG-EDGE calculates combined average delta across all registered events regardless of context. On the surface that seems fair, but in practice it creates a meaningful distortion that I'd argue doesn't reflect true driver ability.

Here's the problem: not every event we enter is one we're actually competing in seriously. Sometimes we jump into a Daily race for credits. Sometimes the mandated car is completely wrong for the track. Sometimes life gets in the way and we phone in a couple of laps just to participate. Those runs can produce 5-7% deltas that have nothing to do with our actual pace — and they permanently drag down our combined average alongside our genuinely competitive results.

The solution is simple and already proven in other competitive disciplines: **drop each player's worst 5% of registered events from the combined average delta calculation.**

Here's why this works:

✅ **It's mathematically fair** — every player loses the same percentage of their worst results regardless of skill level. Nobody gets a special advantage.

✅ **It produces more accurate data** — what remains after removing outliers is a truer reflection of a driver's competitive pace rather than a number distorted by throwaway runs.

✅ **It rewards consistency** — drivers who are consistently competitive across all events barely see their number move. Drivers with wild swings between great and terrible results get represented more accurately.

✅ **It's already standard practice in some sports disciplines** —Many Olympic events like diving drop outlier scores for exactly this reason. The methodology is statistically sound and widely accepted.

For context, my own combined average sits at 2.45% across 124 events.  In Sport mode, I’m E B driver rating because I don’t race.   I exclusively do time trials and only qualify for races to attack the times.  My goal is always 3% or less.  If it seems I’m going to be way off, I won’t bother posting a time.  If I do post something much worse, it’s because life got in the way of logging in before it ended.

That gap exists almost entirely because of a handful of casual daily races where I posted 5-7% deltas without any competitive intent.  Those few runs are doing disproportionate damage to a number that's supposed to represent my pace.

I suspect many of you are in a similar position.

This wouldn't require a massive overhaul of the system — it's a relatively simple statistical filter applied to existing data. And the community rankings would barely shift for consistent performers while becoming significantly more meaningful for everyone.

Would love to hear what the community thinks and whether this is something the DG-EDGE team would consider implementing!
