Absolutely. But so can a DNF -- maybe it means that I challenged myself by getting on a route that was intimidating for me and gave it a really good shot, even if I was defeated in the end.
Conversely, a "dogged" route could be a major achievement for me, and a route I feel I could lead cleanly next time, or it could be a terrible mess.
For that matter, a green tick can mean "I made an embarrassing mess of this route and somehow managed to stay on by sheer luck, but should really have been able to climb it much better".
There's no way that red or green or ticks or crosses will be able to capture all the nuances, and it's unreasonable to expect them to.
I know what's an achievement for me personally, and I've used the notes to keep track of that.
Like others, I like the red crosses because they're debts to settle! Except in a few cases where they're reminders to never, ever go near that route again ...
