Hey i need help with this... so far i am able to achieve a really short horizontal version of this (obviously unable to catch it)

Can anyone teach me how to progress faster?

Well, using the correct technique and just keep shooting will enable you to get use to the movement, therefore each time increasing your height.

If it is a long time already and no progress is seen (long time = 3 to 4 months), it may be because you are using a method not suited for you. What you learn from others may not suit your fingers. Try different methods of gripping the cards, maybe loosening, maybe thumb deeper or so.

If it's only like 2 weeks or 1 month and you are already complaining, then practise some more.

just a tip... cut your thumb nail short
you will have much better control

Its like snapping you fingers. There move can be taugh. But after that its pure feel and practise.
