For info the front is broadly similar, approximately 2 spring rates for per hole position as a rule of thumb ... again not exact.
I have to disagree...

On the rear the difference between inner and outer hole is over 4 springs rates. To equate #65 on outer hole you need the #80 on inner hole, which is 5 rates up...

At the front, the difference is even greater, you cannot equate even the softest spring on the outer hole with the hardest spring on the inner hole, you'd need a spring that's at least 2 rates up to be able to do that.

Also the anti-squat with no spacers is 3 degrees. To get zero anti-squat you need to raise the RR hinge pin holder by 2mm
