That's what causing the jerkiness when you bump start. You always want to use 5th gear for a smooth bump start. Think of it this way. if you are driving 20mph and you want to bump start, 5th gear will be the lowest rpm when you pop the clutch. So there will be less jerkiness. Now imagine if you wanted to bump start in 3rd gear. The rpms would be higher. So when you pop the clutch, the transmission jerks the engine up to that higher rpm, hence the jerkiness.

I've bump started in 5th all the way down to 10mph.
