Of course, assume your dual is going to be the one to find your whole post amusing.
You make LIIs sound rather anal, put bluntly. Don't hate on your PoLR or else I might have to choose LII just so I can get over there and supervise you a lesson.
Nothing wrong with changing plans or adapting to new data as it comes in. The system is in constant need of being optimized, and when opportunity comes to do so, it is to be utilized. Call me a Dynamic if you want, but the situation is constantly evolving and what doesn't keep up doesn't thrive.
I do have a slight tendency towards contingency planning. It's much more mind easing to be prepared for all possible scenarios than to have one general tool set to tackle anything. (although such a set can be a very useful backup in the even that the normal mechanisms fail) It's more of using anticipation as a coping mechanism than anything. That, and it's not fun to waste vital resources, such as the amount of time I DON'T have to spend outside of my wifi-supplied lair.
I can change my own plans whenever I want. If I think something is going to work better, I'll do. Of course, someone else changing mutual plans bothers me. If everything has been planned and is going according to plan, then there isn't too much need to jeopardize the plan. There was very clearly an agreement and I'm going to hold another person to it. (albeit with some slight leniency in the even that words were interpreted slightly differently) I'm open to compromise if we both decide that we don't want to do it, but commitment means commitment. There are pardonable mistakes, but if something is uncertain it should be left flexible.
That being said, almost all of my organization is mental. I seldom keep a day planner and only recently have started using a calender application for managing dates, dental appointments, etc. Other than that, I get a feeling of being defeated if I schedule my time away. Being able to move time around a lot makes every moment feel like every-so-wonderful free time. I could schedule my life away, but I'm not a robot. I have my general environment suited for my ability to enjoy what I'm doing.
In short, I'm anal with organization when interacting with most others. With myself, I let myself "off the hook," if you will.
