no idea lol. dont know how to figure it out

it won't have much at all. its similar to FSR with an extremely low pivot very close to the BB. i'd guess somewhere between 12-20mm of stretch, which isn't bad at all.

thanks! how did you figure that out btw?

its just an educated guess. chain stretch has everything to do with main pivot and/or axle path. first off main pivot is very low. second its an FSR design. FSR as a design has very little chain stretch. basically what you have created here is a big hit. or very similar to a Norco, or Devinci wilson.

and looking at your graph you only sit in 2mm of sag?? whats up with that dude?! thats hardly anything. the bike won't track very well.... for a fully you'd want about 25% to start, however if you are talking about a DH bike its usually well over 25%. most DH rigs prefer to be sagged into about 30-35% sag and 25% sag in the fork.

sooo somewhere around 75mm of sag. my designs sit at 30-36% depending on which design and which shock position you have it set. (all of my 3 designs have 220mm) the single pivot design which i am beginning the building process on is designed to sit in 33% sag (72mm)

yeah this would be no rider just the bike without the rider on it, its how i do all my designs. got bored and made a 10 inch travel version as well might put that up tomorrow the pivot is right next to the bb practically on it so i might put some sag on that
