unbalanced counts and pivot points

I'm currently learning to count using KO preferred for six deck games. Although I know that this is a perfectly fine level 1 count, I've been looking at a couple of other unbalanced counts and have a question.

The Red Seven count for example, is almost as simple as the KO, but it's pivot is lower than that of KO. Does this mean that the Red Seven count will be more profitable, since the pivot will be reached more frequently than for KO? The KISS count has an even lower pivot. Or is this difference so small it's not worth worrying about?

I'm thinking about this particularly because many of the games I play in have rather mediocre penetration, so reaching the pivot point earlier seems like a good idea. Thanks.
