Like some other peers, it took me a little longer and I have used a different path to get there. Although I looked at the Benchmark Data to see the format, I actually used the tools that made me get to the format of the table I wanted, which is a bit different to the table presented. Visually it was more appealing to me.
And I think that is what matters. Honestly, the way the Official solution is put, is very elegant/simple. But it is also probably made by someone who has used these tools for a long time, so they know all the ins/outs. What mattered to me is that I used so many tools, and did a new path. I practiced with tools, and took a few others. I think also it depends on style, because I didn't like their headings and order of columns, so I took the liberty of moving things on my own.
