Clutch modulation at catch point

Hey fellow manual drivers, just out of curiosity...

I just met a girl who drives a Hyundai Santa Fe (SUV) with 5sp, and noticed how she does not even touch the floorboard while she's engaging the clutch including catch point. I thought it was very interesting cuz when I do it, I modulate the clutch while pivoting against my heel touching the floorboard, then immediately after catch point I let the foot off into the air completely. I asked her why, and she simply said she never even considered it cuz she was too short to reach anyway. Yet the catch point was impressively smooth. (Well, I realize that it's a soft, heavy car with worn out clutch, but still for a girl... you know?)

So... I was wondering, how many people:
1) pivot against the floorboard with the heel; or
2) do not touch the floorboard entirely; or
3) other???

Was taught that way and have been doing this for 20+ years of MT driving.

Hmm interesting. So is that the "right" way to do it? I will def give it a try and see how that feels.

There is no right or wrong way. I used pivot on the floorboard with my Civic because it was so light with a really short throw. The subsequent cars have either had a heavy clutch or a really long throw.

So what is the question? Where you "pivot" your foot on the clutch or how far you go past the engagement point?

I pivot my ankle on the floorboard in first gear. Every subsequent shift, be it up or down, foot off of the floor.

The question was whether you "pivot" your left foot or not, and you answered it; only in first gear.
