The stagger looks like outer lanes get a head start, and in a literal sense they do, but it is the thing that makes a curved-track race fair rather than unfair. A runner in lane 8 covers a bigger circle on every bend than a runner in lane 1, so if everyone started on the same line, lane 8 would run a longer race. The stagger moves each lane forward by exactly enough distance to cancel that out. The numbers are not arbitrary; they come straight from the geometry of a circle, and the formula behind them is simple enough to check yourself. Below is the actual stagger, lane by lane, for the 200m, the 400m, and the 4x100 relay, plus why lane 1 and lane 8 are running genuinely different-shaped races even though the finish line distance is identical.
Going around one full bend, the extra distance an outer lane covers compared to the lane inside it is pi times the lane width, and that number does not depend on the track's radius at all, only on how wide the lane is. With a standard 1.22 m lane, that works out to about 3.83 meters of extra distance per lane, per bend. A 200m race has one bend in lanes, so its stagger uses that number once; a 400m race has two bends, so its stagger is roughly double.
World Athletics facility standards measure the running line 0.30 m from the inner edge of lane 1, but only 0.20 m from the inner edge of every other lane. That 0.10 m difference is why the jump from lane 1 to lane 2 is a bit smaller than the jump from lane 2 to lane 3, even though every lane after that adds a consistent amount.
Because a 4x100 relay is run entirely in lanes around one full lap, just like an individual 400m, the total stagger between the extreme lanes across the whole race matches the 400m column exactly. That stagger is built into where each leg's exchange zone sits, not just the start line, which is why the lane draw matters just as much in a 4x100 as it does in an individual 400m. A 4x400 relay is different, only the first leg and part of the second are run in lanes, after which runners break for the inside the way an 800m runner does.
The stagger evens out the distance, but the curve still has to be run well. Film a rep, the AI grades your lean and curve mechanics so you carry speed through the bend no matter your lane.

Each lane is offset by the exact extra distance its wider curve adds, so every lane runs the same total distance.
These are cumulative distances each lane starts ahead of lane 1, using the World Athletics facility standard of 1.22 m lanes and a 36.80 m lane-1 radius.
