now that is with the original steering head angle. so 20-24mm.
then on the other hand, my old 400 has a 22.5d headstock and ran 11mm to feel sweet. originally as a sweet handler it ran 18mm. and 18-20mm was the sweet spot. so a 4d headstock change was worth 8mm of offset change.
I would say 24mm offset on yours if a 570, 22mm if a 450. then however many degrees you change the headstock angle by you should then take off 2mm per degree. you can at most make 2d of difference. that is the tops I reckon. so you are looking at the same as SM at around 17mm offset. the lowering process - well I don't know what you will lower it by but it doesn't change the trail at all doing this.
What normally works on an enduro/MX bike is not directly applicable due to how the tires act and the riding.
As far I can see from the parts list the 2009 570FE has 19mm offset triples, and with this setup itll currently wobble if you let one hand off the bar on the straight. If I am to change the geometry and put the bike more on its nose chances are its going even more unstable, so Id like to have a plan to keep that in check.
Rest assured Im not putting anything on my bikes just because someone else says so or that top racers uses a certain part, I will try what works/feels right
