Six minutes for setup is wild when you think about it, because that's basically the time it takes to make coffee. I did the same thing last fall when I left my 24 pack of Stabilo pens at my parents' place in Twin Falls, and by the time I got them back I realized I hadn't missed them at all. Here's the part your sister is really onto though: the color coding wasn't just eating setup time, it was eating your follow through. Every empty habit box was a tiny guilt trip about a page you hadn't decorated yet. One pen kills that whole problem, because the page is never "unfinished," it's just written in. You can always grab a highlighter later for the stuff that actually matters, like marking paydays or big deadlines.

How long did it take to hit that 94%?

Had a similar thing with my old Tacoma, the rear diff started howling and every forum said drop the whole axle and rebuild it for a grand. Turned out the breather tube was clogged and it just needed fresh fluid, twenty bucks and an afternoon. The grease in these lenses dries out the same way, gets hard and gritty and people think the gears are shot when it is just old lube grinding around. That roller you swapped was probably fine too, just gummed up with the same hardened junk. Half the "send it in" crowd has never opened anything up in their life, they just repeat what the last guy told them.
