In my opinion, this is only a fraction of the work you do for HGL :)
Thank you for your friendly message Hadár - while it's not as much work as maintaining HGL, it is still highly appreciated, and I'm absolutely confident I'm not the only one who appreciates your work with stats. :)
(Without naming any persons, I actually happen to know there are some/many among us HGL managers who really like and appreciate stats).
Be it a little or big task that one decides to take on, all these kind of things make HGL little bit better, little bit more interesting, and share the workload a bit...
Your contribution is one good example, MrJ's help earlier on another one, and as a third example I could mention LennuK. who has also been helping with certain HGL stats/comparisons for couple of seasons, and has also promised to help in other HGL related tasks in the future.
As I said, for me community is for me one of the best things in HGL.
If I had the financial means, then I could even help (to some extent for) people to get together in actual HGL meets (as I proposed), but unfortunately that's where I have to draw a line, as financial restrictions step into the picture.
So we shall see if actual meetings can be arranged (cost, time, finding common time suitable for many simultaneously, etc) at some point(s)...
