WoW - What's your guess at time per level?

I'm looking to see what's ahead when my lock's are higher. So what does everyone estimate how long it takes each level, at your current level, and how many characters.

Ex. If I'm 30, I'd say how long I think it takes to dual-box 2 characters each level currently.

And if anyone asks why?, we could just use it to make a chart for newcomers to see how long the average is ranging from 2-5 characters :P

I didn't track it until SM+ but at 37 when I started there, I was pulling in about 18-30k per hour clearing the SM cathedral courtyard depending on how much I goofed off. Prior to that, I was pulling about 10-14k/hour running quests. By the time I hit 41ish, I was only pulling 15-18k/hour as most of SM cathedral was green to me.

At 42, I went into RFD and was pulling about 15k/hour AoEing down the groups in there. I'm starting Uldaman tonight and I'll let you know how that goes.

This is with a full 5-box team. With just two, I would follow Jame's or Joana's leveling guides as the collection quests will not be such a huge time-sink.

Level 1 to 65.5 = 12days 10hr or around there. With 1 Priest 4 Warlocks.
Note from 62 to 65.5 all done on rested.

Edit: SO I guess around 15D on Full rested after 60 or 18D without.

hm level 48 - 6 days 20 hours (pally + wl) atm :>
