Hmm - my boss just confirmed that I now have a slightly changed role that will involve 4xDONE4 this year (including my currently bought and paid trip in March). Currently Plat - first trip planned to earn 57K eqp. So in theory if they run this all year I could have obtained EXP Status before my first trip - damnit!
EXP will this year cost me about US$17K - being 2xDONE4 - although I will get EXP about 1/2 way through the second trip I think. Mind you a lot could happen between now and then...
