If you can't be confident that the information is giving you the best outcome, it can be verified for any bike as follows;- bike on stand, ratchet strap from swingarm over frame to other side of arm, pull suspension up until sprockets and swingarm pivot are all on the same plane, set chain to have 13mm (1/2 inch) ot total movement like that as this is the tightest it'll get.
Now lock it off, release strap, and measure what you've got with the suspension hanging loose. Write it in your manual with a note for future reference.
Always did motor-X bikes like this as they moove so far, gets minimal slack without pulling the bearings into load as it moves.
