Lets say you go and look at all of Afterlife's raids against Trakanon, and roughly gauge the times between the kills, you'll get 38 kills in about 170 days, which is a kill every 4.5 days- there's literally no way he could've been a 7 day spawn even with patches at that point.
38 kills from 06/25/2000 to 12/04/2000, that's 38 kills in 162 days, at very minimum that's a kill every 4.263 days, it's literally mathematically impossible for it not to have been a 3 day spawn.
There's even three dead periods of no Trak kills spaced 14, 11, and 12d apart. The average still says they killed him every 4.263 days.
Here was my rough estimation of time inbetween Trak kills as reported by Afterlife's DKP site; (You can check my data here;

Trak kills, days between; 5 6 3 5 3 4 4 4 1 2 1 7 2 3 3 3 3 3 3 3 14 2 11 1 5 4 5 5 8 4 5 4 7 1 2 12 3 1
