Thank you very much for these posts, it's really fun (and scary ) to see how much the 'new' quads count is going up! One thing though, because the poor guy is always forgotten: Vladislav Sezganov has landed the 4Lz as well, though I don't remember when exactly he did it (after Mroz, before Jin).
Vladiwhat Sezgawho?
A little googling.
https://en.wikipedia.org/wiki/Vladislav_Sesganov
Vladislav Dmitriyevich Sezganov or Sesganov (Russian: Владислав Дмитриевич Сезганов; born 3 July 1988) is a Russian figure skater. He is the 2012 Golden Spin of Zagreb and 2011 Gardena Spring Trophy champion.[1]
Sesganov is the first European skater to have landed a quadruple lutz jump in a sanctioned competition.[2] He has also practiced quad lutz - triple toe loop combination.[3]
On August 6, 2014, Sesganov announced his retirement from competitive figure skating

He did a solo 4Lz with a turnout GOE -1.00 https://www.youtube.com/watch?v=XAbE4QHXRXw 4Lz starts at 1:04 (Any comments?)
Will credit him in my next quad progress update after Cup of China.
