I don’t know, that’s what’s confusing me here. My numbers and own experience of awakening mythics are aligned. The only other person who’s gem income + hatching I know well is Raghnius, who also has results aligning with them. He also knows and follows my exact hatching strategy - detailed in this guide: KD's Egg Hatching Guide
My best guess is almost everyone drops the mark somewhere. Either poor hatching prioritisation, missing shrines, not playing all content, not a veteran getting 6* tickets, etc.
The number of F2P veterans who have played consistently for the past 5 years (while mythics exist) is probably very small to begin with.
