Red Sevens Counting system

I have a question.

I ran the data for red sevens on single and double deck and the results came out better than using hilo. Higher EV, less risk of ruin, and a higher score. All were run with the same rules.

This count is actually easier than converting quarter deck true counts.

So at my observation, the red sevens represent penetration, or how deep the deck is at the time. Basically the deeper the deck the higher the bet. So if the red sevens represent penetration, why not start a single deck game out and after about a third of the deck add one and at another point in the deck add another one. It seems this would take out the problems when the red sevens come out in the first hand, and when they never come out. Since it is an average why not just add a point at th averag points in the deck.

Seems to me that this would be even more accurate than red sevens, lowering you risk of ruin even more, and increasing your EV.

Please give me feedback on this theory and tell me where my flaws are.

First of all, Red 7 IS stronger than Hi-Lo. It has a higher BE, PE, and IC. However, it is an unbalanced count and some people (like myself) may have issues with it. At different points in the deck, unbalanced counts will overestimate or underestimate the true edge. While in the long run it will balance out, I like having the security of knowing that what I am betting is correct based on the current true edge.

The red 7's are counted because they are (more) advantageous for the dealer, but not as much as 4,5,6. Therefore, only half of them are considered. If you want to solve the problem where red 7's come out early, you may want to consider counting all the 7's as 1/2. While being slightly more accurate, it will transform the count into a lvl 2 count, which may not be desireable.

this is true. unbalanced counts tend to underestimate the beginning, and overestimate the end.

While in the long run it will balance out,
Yap, almost everything does.

I believe him when he states this personal preference.

This is verified by a quick look at a Effect of Removal table.

Count all 7s as 1/2 instead of just the Red 7s as 1, sounds more accurate to me, and it is!

Yap, using different tag value for some of the cards would make it a lvl 2 system, true enough.

I attest.
