What you posted is pretty much self explanatory.
The secret is to have the engine RPM equivalent to what it would be if you were already in the gear you're shifting into. Once you grasp that principle, you don't even need the clutch to make a smooth shift.

Did you ever get accepted to a driving school. If so, they would teach you proper shifting techniques.

It's always funny, reading how guys' are trying to help on shifting. Yall are right, not that, but shifting is something to be learned when driving, but sooner or later, they get the hang of it. We all had to learn how.

Feather the throttle. Take the torque off the transmission either with or without the clutch and shift to neutral. As the tach seeks the next appropriate rpm, make your moves with the stick and clutch. Here is my point. Do not wait until the tack is correct for the next gear. Make your moves early so that you can slip it into gear before the tach goes past the mesh point. Let's say the tach is dropping for an upshift. As the tach drops the transmission is in neutral with the clutch engaged. Just before the tach reaches the desired rpm, make a simultaneous move with the stick and clutch. Don't hesitate, or you will have to re-accelerate.

I thought double-clutching meant that you use the clutch to start & stop rolling and never in between.

You can't learn how to shift or back from reading books or internet ...even an instructor is pretty useless ,because you learn these things by feel ,which can only be done by driving .

When I was in school, I had a lot of trouble with learning how to double-clutch. I'd driven a standard shift car since I was 16 (16 years doing it), so that's what I was used to. That's when the instructor explained to me how to float the gears. After that, I gave up on the DC thing. Of course, now I'm in an auto and only use the clutch to start & stop anyway.

Newer autos don't even need to be clutched to start/stop...which is the only time I see a clear benefit to the auto . |
