but more important to someone who spreads his bets with the count it, like late surrender, reduces your variance so that as your edge increases your optimum betting unit is higher and thus you make more money.
If I got you right you want to know by how much your advantage increases if the TC goes up by one unit with the rule set you gave.
In an old output of my CA-program I found the following: between 0 and +3 the advantage increases by 0.55% per unit.For higher TC's it increases faster, more like 0.67%.This is due to the insurance effect.
Off the top ES10 is worth 0.25%.
it is not 0.2% for sure.
it is between 0.09-0.11% / TC for extra adv E10.
total 0.59--0.61% / TC.
extra gain of full surr=0.65% for full surr -0.50 no surr=0.15%
extra gain of late surr=0.58% -0.50% =0.08%
so it is 0.08-0.15% in wide range.
excl. stgy & insur, gain.
ES10 reduces the house edge by 0.24% to be exact. It's main benefit other than that is variance reduction which when factored into betting allows for larger bets at each true count. You would also have a higher edge at each true count because your starting point is higher. Aside from that I don't know what else to say.
I've looked at Simulations for Zen for s17 ds ls and s17 ds es10 and for both the average change in expectation for each +1 or -1 of true count is 0.34% for both sets of rules. There seems to be not much change in advantage for ls versus es10...but variance for equal bet ramps is lower for ES10. In fact, the win rate for h17 ds es10 versus s17 ds ls rsa are almost equal with a very slight advantage going to the h17 es10 game.
