For Las Vegas Strip (2 Deck) game and 50% penetration
if you use Hi-opt II and spread 4 you will have an edge of 0.63%
You have positive expectations as long as you spread 2, but in that case edge is very small 0.26%
With bankroll of $ 3000 and if you spread 4 you can expect to make $6 on average per hour.
For the same bankrol if you spread 2 $1.33 per hour.
But if your bankroll is $50 000 and you spread 2 you will be amking on average $22.86 if you spread 3 mmmmmmmm $63.2 bucks per hour nice!!!! What a job!!!
Yes you can make some money but it will depend on your bankroll, because you do not want to spread a lot in hand held games.
