Ive ytried 3 different ways of alignment. Ive used the marks on the swingarm, ive used a metal straight edge on the faces of the sprockets, and ive used the 2 strings between the front and rear tyres method. Using any of the three puts the other two out

Start with the markings, spin the wheel backwards, then eyes and ears works for me. It'll be quite obvious if it's misaligned, and also obvious when it is straight when it just purrs with no chain movement or clunky noises.
It's very important that the bar connected to the caliper is loosened off first, then just take time slowly nipping each side up using the adjustment nuts.
Not something you want to rush, because once it's done it stays in position for ages and unless you're ragging the bike regularly it will rarely need any adjustment for ages.

Thats where Im at now. Spin the wheel and look how the teeth enter/leave the chain. Cant be too far out, done 2 trackdays like that with no hassle and no signs of undue wear and tear. Im happy

Also how do we know that by lining up the wheels that you are lining up the sprockets. Or how do we know that measuring to the swing arm is either lining up the wheels or lining up the sprockets.
Surely to line up the sprockets you need to get access to the face of them and do it from there, but then that will not necessarily mean that the wheels are lined up. As it has been noticed that you seem to get one right and it puts the other out.
