you can be flying a t1 mining barge in a couple of days, under a month for decent skills. you can be in a t2 exhumer with very solid skills in under 3 months. (I know this because thats how long my training queue for my mining alt is)
so the real question here is, how new is new? sure someone a day old won’t be pulling in 100m+ an hour, but why would we ever expect them too? under a month though? maybe possible, 3 months, easily. that really doesn’t seem like too long of a wait.
