it's like sex, you'll get some when you're ready
but anyway i probably shouldn't comment cause i haven't counted cards for a long time, never was all that good at it, cut corners, got frustrated often, that sorta thing, still made a bit of money, luck or skill, lol. besides, 12 years ago when i did give it a shot one could actually find some good rule sets sorta thing. i dunno how folks still manage to hang in there counting cards with the difficulty of finding 'good' games.
that said, you might consider going to a joint and just playing some shoes just playing hopefully perfect basic strategy. that'll give you a bit of skin in the game, give you a real deal experience, sorta thing. give you an idea of how you think your doing counting but not betting up. i mean heck, a game like say 6 decks, H17, DAS, Late Surrender, Peek, Estimated casino edge for these rules: 0.58 %. what would you expect that to cost you?
a long run average of fifty eight cents lost per one hundred dollars bet, sorta thing. but of course short run, fluctuation may inflict a bit of pain or pleasure.
but anyway, then you'd have a bit of skin in the game. from there you could make a sort of non math certainty equivalent calculation of if or not you really want to give actual card counting a shot, sorta thing. similar to CE calculation where one has a proposition bet offering, of would you bet $100 on a coin flip or just take a free $10, or would you bet $50 on a coin flip or just take a free $5, or would you bet $10 on a coin flip or just take $1, on and on, ..... but you had to make one of those bets (maybe a condition of a free roll promo sorta thing).
but anyway, i'd recommend never forgetting your really advanced (imho) idea of not wanting to waste time, as you stated, " I'm afraid to waste time in ...".
if your old like me, you don't want to wake up to late and finally remember that it's everything, all about
time!
