You must have basic strategy adjustments based on count memorized in order to be successful in counting now. gamemasteronline.com has the most important ones, I could also give em to you if you wanted.
I use the Hi-Opt I with a side count of aces, the best count system in terms of usability and accuracy, even without side counting aces. With this and proper spreading, leaving on bad counts, starting shoe when alot of smalls on felt, & some other lil tricks, you should be able to expect +1-2 top bets per hour.
So if your a $10-$80 player, expect $80-$160 an hour if you've done everything right. But most likely you'll either have a huge win or huge loss for the day which balances out in your favor in the long run. Definately too stressing to expect sole income from this but I look at it like a profitable hobby, and I get great comps as well to boot! Been doing this about 4 years but only did my learning during my 1st year, from there it's just a matter of speed & repetition which gets better quicker than you probably think.
