DR doesnt go off after 24 hours. its reset after 72 hours. But the impact of hits in the time before 72 hours are subject to a half life which is between 12-24 hours on this server depending on relative military strength (which unless you did the hit with perfect information or spied the attacker and defender at the time of the hit is an unknowable unknown).
Then there is country:country DR which has no reset time but a 168hour static half life.
the stolen acres part is affected mostly by the non-specific DR. So this hit:
2021-02-19 20:48:31 PS Dadali (#4) Siffredi (#37) 374A (403A)
Has quite a lot of stolen acres. But country:country DR is insanely high which is why there are only 29 ghost acres captured or less than 7.5% of the total acreage of the hit.
The first hit:
2021-02-16 13:51:00 PS Dadali (#4) Siffredi (#37) 807A (1584A)
Had almost 50% land gained as ghost acres.
Very informative example.
Half lives, as you know from our physics classes is applied as y=x*0.5^(t/t_half)
x = the quantity of what is subject to the half life(the number of hits at a certain time within 72hours)
t = time elapsed
t_half = the half life
y = the quantity left at time t
