Sorry, but I think you are..mis-remembering..One year ago a new server started where i began to play. So now ressource boost from others what so ever and it took me 18 weeks (2 tournament cycles) to become full boosted (500+ Relics for t1-t3 boosts). Even if you take double the time it`s still faster than in was intended by Inno.
Full boost requires 500 relics to get 700%.
I dont think it very likely that you got 250 relics every weeks for 18 straight weeks starting in Chapter1, and the ones from The map aren't making up the difference.
You can check elvenstats and find low chapter players who have not set their boosts-the website defaults to the average. I would guess that the average is between 36-45 weeks to get full boost, if not much longer
