proletariandan -
This is the best way I can describe it with my manual transmission :
1 - EOC'ng between 25 and 35 MPH, key already in "start" position.
2 - Push clutch down with foot
3 - Put in 5th gear
4a - Let up on clutch quickly, but not all the way, just enough to "tap the flywheel", is how I like to think of it.
4b - Push clutch back in right away to let engine turn over and start revving.
5 - Re-engage 5th gear and be on my merry way.
When I do it right, there is almost no bump in the start. This might be a form of double-clutching, I don't know.
In 5th gear below 25 MPH, the bump in the bump-start gets rougher. At 20 MPH, I think that 4th gear is best for my car.
But like everyone says, your drivetrain will have a different sweet spot. If I were you, I would find an empty road and experiment with "how low can I bump smoothly in 5th gear". Below 20 MPH, I usually use the starter.
