Smartthings Groovy scheduling limitations workaround

Question

According to Smartthings documentation, only 4 jobs can be scheduled at once. I'm curious if this limit applies to all applications installed on a hub, or a namespace, or a single application. Even still, I have two single applications that require more than four scheduling times. A saltwater light controller and a similar freshwater light controller. I also of course have other applications in the household that use scheduling. I can change the namespace to separate them if needed, I wasn't even sure of the best practice. You can view my code in the links provided, but does anyone know a work around to this limitation? I know I could probably write something up where it applies runIn() after a start schedule() to lower the count, but it doesn't specify if both runIn() and schedule() combined count against that limit. Anyone have any experience with dealing with this?
