And I know you know a lot more about how real processes behave than I do. I'm not saying (or thinking) anything negative about you. I'm just trying to throw random thoughts into the mix just in case some small part of what I say is useful inspiration for someone else such as yourself. It is probably the case that the idea I suggest is BS and makes no real difference or makes it worse anyhow. :)
