FP Mages and DPM after Big Bang: A tough question

Amp is not affecting DoT.
Elemental weapons are being used supposing you would choose poison/lightning over fire/ice (obviously), not affecting DoT.
Infinity is not factored since it works the same for both mages (does it affect DoT? Haven't heard an answer on this, if it doesn't it will change some things).

I'm pretty sure infinity doesn't affect DoT.

Also, this is assuming the F/P is timing everything perfectly. Right as one skill's DoT is about to run out, he uses another one immediately. And for higher levels, when runs get fairly fast, the 10 seconds or so to initially start up the DoT skills probably take a little chunk out of the running time. Of course, the I/L is ideal as well, but there's less room for error when there's only 2 DoT skills.
