I hear you, and when I use to race we did all of that, and because we did all of that I have an ok brain, not the best brain in the world, but ok enough for me to keep a log in my brain. At this point and time I don't want to come home and spend another 30 minutes or so downloading stuff and reviewing stuff, to me that's work and I don't want that in my cycling life at this time. If I decide, and this a big IF, to go back into racing, which will only happen when I retire if it happens at all, then I'll consider getting a bike computer that does that sort of thing and keep a track of stuff because then I'll be retired and that will be my new job. Right now I have to many jobs, I have my regular job and I have my property business job and I just don't want to add another.
I doubt if that makes sense to anyone, it's just how I'm wired.
