Hello to everyone who is curious about me jumping from rank 26 to 8. I analyzed it and I want to say here that is purely accidental. It was one of my very first submits when I was just trying around.

My first “serious” submit was minimizing the score on the training set with six fixed ambulances. It got pubic score 40.421, private 44.288. After this, I tuned this with some heuristics, choosing new positions for every time-slot. That brought me down to 40.165 / 44.083.

At least for my submits, the correlation of public and private score seems quite good, except the “winning” submit with 40.616 / 43.832.
