That's a good point about not being able to test your new solution on the same input that you know you got right, Dmitriy. A few other thoughts:
- I don't know whether the UI makes this clear -- note to team, hopefully there's a really clear indication that you still have points from previous submissions -- but *you can't lose points you have earned on a visible dataset*, no matter what you submit later. - I agree that it isn't without penalty, but I don't think 4 penalty minutes is a very significant cost. I also don't think there's anything wrong with that cost being present. - When writing an analysis, it's often helpful to first consider a simpler version of a problem before you consider a more complex version. I believe that's what they're doing here. - Although there are a couple of things that make it less appealing -- lack of ability to test on a Google-generated dataset, and the extra 4 penalty minutes -- it's still totally reasonable to code up a solution that solves the Visible and not the Invisible set. For example, what if you don't know *how* to solve the invisible one? Or, as we've discussed here, what if you're planning on submitting the Invisible set later if you get a chance?
