You are talking about something that alsmost equals to what I made some time ago, reffering to your point nr.2
Thank you iasenko, that brings a lot of light for what I was looking for. OMG, only 15 members managed to get to Hero so far? WOW! They are very, very few.
It was interesting to see these 15 out of how many in total managed to get to Hero, to see a percentage, but, as LoyceV said, it would be too much work for this statistic...
DdmrDdmr already has all what you asked for. He has a tableu site for this.
Thank you as well, hd49728, I'll take a look into it!
I'll skip this one: this requires scraping around 2 million profiles.
Thank you, Loyce, I understand the difficulty of such an analysis.
Thank you all, once again. I'll close the topic now, as the subjects are solved.
