If i have a bank roll of $10,000 and i want a 5% ROR should i have a betting range of 1-12 units with a unit being $10 and my max bet being $100
That would be a 1-10 spread.
It depends on what game you are playing and how you are playing it.
There's no one answer based on what you say. You could spread $10-$100 with with $10K and your risk could vary all over the place in different games with different pen etc.
if im playing hi lo in 6 deck games with 75% penetration
lol thx but what if i divide by bankroll by 500 to get my betting unit
lol thx but what if i divide by bankroll by 500 to get my betting unit
and then when im playing i would take the true count and subtract the offest which = 1
and then multiply that number by the unit.
like say i have a $50,000 bankroll i would divide it by $500 and get $100 as my betting unit and if the true count was +3 i would subtract the offset and get +2 and then bet $200 on that hand.
and i would change my betting unit in between trips and after a large swing.
Would this strategy be effective and have a low ROR?
Actually what your describing is the old MIT system of betting. It will yield a low ROR, it is an ultra conservative approach. The problem with it is that the betting ramp is not really what you will find to be optimal. Most ramps will find you getting max bets out at a TC of 4 or 5. With this system you will not be getting out very many max or large bets out as you will find rare instances that you will find TC's reaching in the 7 and beyond range. The key to this system is having a large enough bankroll that your minimum bet is less then your unit size but can still be big enough to be able to meet at least the table minimum.
For example, what was common was to have a unit spread of 1-6, while still having a bet spread of 1-12. If you had a unit of $20 you would bet $10 in neutral and slightly negative counts ( important here to not play too many hands at a TC below -1) and once the TC reached 2 you would start laying out a 1 unit bet, raising it as you said, TC -1 to give you your betting unit. The problem as I said earlier is your max bet will only be coming out at a TC of 7 and that won't give you a lot of max bets. The good side to it is you will be betting proportionate to your advantage and at around .5 kelly with 500 units as a bankroll, at what would be much less than a 13.5% ROR. The down side is a loss of EV due to the less than optimal betting ramp. I have recommended this for 2 kinds of players. Those who have very large bankrolls that are not repenishable where the unit size is large enough it makes for decent earnings anyway, as well as low risk. My team has used this method in quite a few situations, except we are playing at even a more conservative Kelly coefficient then even .5. Or for those that are new to counting and haven't grasped how to lay out the optimal method of play. This system will gaurantee a positive expectation no sim required, just maybe not the one with the highest earning potential. I will confess I have pushed this way of betting on many that have played due to the fact I was assuming most weren't putting the time in to lay out there games. I have since been proven wrong by many here as I have seen some impressive displays of detail in game preparation. That is a good thing. For those who still wing it with just the knowledge of how to count, this method is for you.
so is using this strategy only good if you have a big bankroll ?
and what betting strategy do you use and find best?
If you had a unit of $20 you would bet $10 in neutral and slightly negative counts ( important here to not play too many hands at a TC below -1)....
o ight thx
and in blackjack blueprint Rick Blaine writes about optimal betting but i dont really understand it all the way
if playing hi lo in 6 deck games
he says to get the betting unit by dividing the bankroll by 100 to get the max bet because your bankroll should have 100 max bets
and having a true count of +3 or less bet 1 unit
+3 = 1 unit
+4 = 2 units
+6 = 3
+8 = 4
+10 = 5
+12 = 6 units
so would this betting strategy be effective and have around a 5% ROR
having a true count of +3 or less bet 1 unit
+3 = 1 unit
+4 = 2 units
+6 = 3
+8 = 4
+10 = 5
+12 = 6 units
so would this betting strategy be effective and have around a 5% ROR
That looks like a betting strategy for an unbalanced count to me. For a balanced system you generally want to raise your bets around +2 and hit your max bet around +5, but it depends on the game and your playing style. Some games give you an advantage at +1 so you can raise your bets earlier. If you are backcounting then you can wait longer to hit your max bet, maybe around +8 or so. For play-all you might be making your max bet around +3 in order to offset all the negative hands you're playing. It can get pretty complicated...Here are some links to what other people use:

Rick Blaine in Blackjack Blueprint says
0 or less 1
+1 2
+2 4
+3 8
+4 10
+5 12
would that be effective and have a low ROR% ?
That would be effective. It would be better if you could avoid negative counts, but not everyone has that luxury. A bigger spread would be more profitable, but it may not be realistic in your situation. So many things depend on the circumstances under which you play. You will know what styles of play you can use, what table minimums are available and what kind of bet spread you can get away with better than I.
The RoR will depend on the size of your bankroll. You probably want at least 800 units for something like that. Chapter 10 of BJA gives EVs and RoRs for just about every set of rules, penetration levels and betting styles that you are likely to find. That will give you a better idea of how to optimize your strategy.

thx and i dont have that book do you know of any other way were i can find that info
A simulator program will also give you that information, or you could get a very general ballpark figure from a spreadsheet:
