In general, about unbalanced systems

They are more accurately balanced in that the assessment of the advantage, as well as the size of the deck, (in contrast, "by eye" in balanced ones) in unbalanced ones, this makes an array of cards for you (much more accurately). In accordance with this, you have a more flexible betting strategy, and an assessment of the advantage (which is reflected in more competent bank management for the game). For example, according to Hi Lo, you do not change the bet at +1.5 (because you are not sure, for example, +1.5 now or +1.3).

If you play according to an unbalanced system, you feel much more confident in these assessments. Do you understand my point? For example, according to Hi Lo, your betting strategy will be 1,5,10,15,20, then playing on an unbalanced one you will get 1,5,7,10,12,15,17,20. This is due to a more accurate estimate of the edges of the real account, such as +1.5 +2.5 +3.5, etc. In this regard, the win rate will increase, and the dispersion will decrease. You can clearly see this in simulations. On good cuts, this is especially noticeable.
