So he has done a 2Lo at the end of combination (granted, it was 7 years ago), interesting.BTW, since I was looking at previous protocols I found something interesting. His SP layout usually doesn't change compared to his FS layout. I actually thought NDP & R&Jv2 has a similar layout except with the order of the quads but when I reviewed the scorecards the 3 jump was actually 3Lz+2T+2T. He did it at GPF, Nationals, 4CC & Worlds. Findlandia's FS layout was also different than the GP series, it has 2 3Lz combinations instead of the 2 3A combinations.
I think SP layouts change much less because they have much tighter restrictions on what solo jumps/combinations are allowed, maybe as a carryover from 6.0 when the SP used to be the "technical program". LPs aren't called the free programs for nothing (although, with Zayak rules and whatnot how free is it really lol) I think Chan helped popularize the __+1Lo+3S jump in recent years.
EDIT: Thank you echotpe for the poll, I voted!
