Running-count strategies like REKO, K-O, Red 7 and KISS work essentially the same except that the ranges move very differently. One weakness of these strategies is the lack of opportunities near the start of the deck where the count underestimates the advantage. However, this is not as large a problem as many people believe because there are not really that many opportunities in the early cards anyway.
From an Initial Running Count (IRC) of -20, we see that the upper range of the count increases much more quickly than the lower range as the imbalance in the card count values nudges the count upward. Unlike the true count ranges, these ranges expand and then start contracting again near the end of the shoe. This is because there is a smaller range of possible running counts when the number of remaining cards is low. There is a larger range of true counts at deep penetrations because you are dividing by a smaller number.
