Attached is a PDF comparing CC for the most important strategy changes of HL w 7m9c top 6 and EBJ2 / 2.
So EBJ2 / 2 is a level 2 count. I was trying to keep the level one HL.
So there are two questions,.
(1) Is it easier to convert from HL to the EBJ2 / 2 than to add the 7m9c to the HL?
(2) What are the comparitive strenghts of EBJ2 / 2 and HL w 7m9c top 6.
If you look at the attached PDF. you will see that the EBJ2 / 2 is HL + (1/2)*(7m9c) which is what is used for betting. So the betting efficinecies of HL w 7m9c and EBJ2 / 2 are equal since they are the same count. Half of the SCORE gain of the HL w 7m9c comes from the increase in betting efficiency.
So now lets look at the PE. I broke this down into regular blackjack and LS.
For regular blackjack, the average CC of both the EBJ2 / 2 and HL w 7m9c are approximately equal.
So the conclusion is that if LS is NOT offered, then EBJ2 / 2 and HL w 7m9c are approximately equal.
But if LS if offered, you can see a substantial increase in LS CC of HL w 7m9c vs EBJ2 / 2.
The increase in the LS CC gives the other half of the SCORE increase of HL w 7m9c.
The increase in the average CC of EBJ2 over HL for LS is 71.8% - 67.8% = 4.0%
The increase in the average CC of HL w 7m9c over HL for LS is 78.3% - 67.8% = 10.5%
So for LS, EBJ2 gains (4.0 / 10.5) = 40% of the HL w 7m9c increase in CC.
So half of the gain in HL w 7m9c SCORE is from LS changes and EBJ2 gets 40% of that gain.
And EBJ2 gains all of the HL w 7m9c gain in betting since it is the same count for betting.
So my prediction is that for LS, EBJ2 gain in SCORE over HL is 50% + 40%*(50%) = 70% of the SCORE gain of HL w 7m9c over HL.
So the final conclusion is, if LS is offered, you swtich from HL to EBJ2 / 2 your SCORE will increase approximately 70% of the SCORE increase if you switch from HL to HL w 7m9c top 6. If LS is not offered, both count systems are approxmiately equal.
But EBJ2 is a more difficult level two count and HL w 7m9c are two simple level one counts.
So there are your choices.
The HL players I know would never swtich to a level 2 count.
And if they did switch to the EBJ2 /2 they would obtain 70% the gain if they switched to HL w 7m9c Top 6 if LS is offered.
