Hello guys, I've progressed decently so far however I've hit a wall on deck estimation. I don't know how to train and I'm terrible at it. I have bought a lot of bee packs of cards and arranged them in half deck increments on the table from 0.5 to 4.5 yet I'm still not getting it right 100% . I count down 3 packs in under 1 minute, I can make all the computations related to true count conversion, betting size, whatever, yet I'm stuck at this single non mathematical skill needed.
So, to conclude, what's the best way to train in deck estimation? Looking forward to your answers, thanks.
