How much would you add to a 400m relay split to estimate their 400m open time?

.5 - 1.0 seconds, generally.
Your standard "good" high school runner will split 50.0 often, but have a pb of between say 50.5 and 51.0. i feel like this is reasonable.
in reality though, there are many factors that go into this. if the split is FAT ala NCAA's then probably more like .3 - .6
and obviously i'm just guessing here.
Depends on which leg

first leg needs no adjustment, of course... but all the rest is roughly 1 second difference (divide the split by 98.125% -- at 47-49 it's .9 seconds, 52-55 seconds it is 1.0, etc.)
not true.. the anchor leg needs no adjustment. they are getting the stick before the finish line and have to run all the way through the line so its the most accurate leg. if anything its a lil longer than 400m

You're not supposed to time the runner, you time the baton (and when you do so, each leg should be 400m). Every leg should be 400m, but only the first leg does not have a running start.

I hope that you are joking.
The right way to get split times is at the 400 m mark, NOT at the handoff. As such, each leg is EXACTLY 400m.
In reality the anchor has the biggest advantage of all of the legs since anchors only suffer through the lost time of the inevitably imperfect handoff once but get the running start just like legs 2 and 3.
Adjustments should look something like:
Leg 1: 0.0 sec
Leg 2: 0.6 sec
Leg 3: 0.6 sec
Leg 4: 0.8 sec
2 seconds.
Is this true? Where's the science
Well, Michael Johnson has the best open and split time ever.
43.18 vs 42.9 (anchor)
So about .3 s there.
Had he run more relays his split would have been faster.
i use .7
and teach the outgoing runner how to match the speed of the incoming runner.
it is always better for the outgoing runner be a little fast and have to slow down a tad, than to be standing there and get run up on by someone finishing a 400. it is in fact, inexcusable and a sure sign of coaching/non-coaching.
also if the outgoing runners are facing the stands instead of the infield, you know they are not coached.
I anchored my HS realy in 51.89, but have never broken 54 in an open race, although I only did a few of them.
What about Indoor (200m track) split compared with open outdoors?
Jason Lezak, is that you?

No... answer the question somebody?
