Just green myself too. After my trip starting next week I should make it to silver. 2 longhaul sectors and 4 short/medium haul all in C and on PL outfitted airplanes. No chance of upgrades unless they allow me to fly the plane.
I am hoping to reach Gold by January as I am planning a trip to Auckland and EVA has great fares to AKL from TPE in PL. I doubt I would make it to Diamond in a year except with the 8 year rule unless that changes at one point too.
