I can do it, it does get trickier with newer cars/more sensitive brakes. Octavia currently has very sensitive brakes, quite tricky/takes a bit of getting used to. Still, it has a tiny engine and I have to keep the turbo spinning somehow!
Learnt to do it really when I had an old Golf that didn’t idle right when it was cold, I do find I have to know the car before I can do it well.
Oh and it’s worth practising just blipping the downshifts to match the revs first, otherwise you’re trying to learn two things at once.
