E90 330i Best Launch RPM?

What is the best launch RPM for a E90 330i with sports package and 6MT? Assuming stock sport tires, dry warm pavement and traction control off?

I tried a to do a bunch of searches and came up with nothing?

This continues to be one of the best drag racing launch tips I've come across on the intarweb.

The take away from it that I get, is that there is no ideal "launch" RPM. It all depends on the condition and available grip. More grip, launch higher. Less grip, launch lower. About the ONLY general guideline he's given is try to launch above peak torque so as the tires grip and the tach drop, you'll be in the meat of the torque band.
