some very rough estimates
You didn't specify penetration, so I'll just use a 1.5 deck cut. If you play all (don't leave any negative counts), don't use any cover, always play one hand at once, and spread 1:12 using a ramp of: 1,3,8,12 units @ TC=0,1,2,>=3, then you need about 1650 units, or $8250. If you Wong out as soon as the count dips below TC=-1, then you need only 1325 units, or $6626 for the same 5% ROR.
If you don't play any negative counts, backcount and come in with $15@ +1, and max at $30@ >=+2, then you need only around $4000 for your 5% ROR.
I just made some generatilities for spread size and such as you gave no such specifications. I did this on Norm's CV DATA. Even those people who know how to do the math generally get one of these little tools. BJRM and CV Data are both very good. You can put in a nearly infinite variety of parameters. I advise you look into one of these products. Most people end up playing a variety of different types of games. This will let you know how you can play at any type of game with your given bankroll and remain within your level of risk tolerance.
