I count mostly as a hobby with the local casinos. I currently use Hi-Lo and use a $10 unit size and a 1-10 spread. Running it through CVData, it seems like with the games they have around me, Halves would increase my average hourly winnings (if played perfectly) by about %7. At a $10 unit size this is mostly negligible, about a $1 increase hourly. Definitely not worth the time it would take to learn a level 3 count. Changing the unit size to $25 changes the hourly increase to roughly $3.50. Since I play as a hobby, maybe about 20-30 hours a week, this would give me about an average extra $3-5k a year. I'm still not sure if it would be worth it at that point. What do you guys think? At what point would you think it would be worth to switch?

(For information, basically every table here is 6D, DAS, RSA, ~75% pen, H17).
