I think your getting in to far a bit to quick... its great to see your enthusiasm but really it takes a lot of practice not just reading. Its like when you first learned to drive.. sure you could read about it all day but that didnt mean you were any good once you got in the drivers seat
36sec or whatever it was is good but i dont think thats really all that fast and may not keep up with a quick dealer... try getting it down to 11-15 sec at that point you will need to turn the deck upside down and just push them over into your other hand as you go.. you can never flip that fast... and if you can i want to see a video!
another thing is accurate deck estimation how are you with that?
also you will want to practice with music and tv and while talking and being talked too. That is one of the rather hard things to do. Keeping count and being able to talk isnt easy and that just takes time that you havent had yet distractions are a bitch at first!
def keep with it and youll be able to learn fast enough but dont take it to fast
im 20 as well and have been going to indan casinos for a while
