Grn14, my theory on that would be different to yours perhaps.
A setup on a bike at the track is a blend of conditions on the day, tyres on the day, heat on the day, how many lefts how many rights, were are you fast were are you slower and so on etc. You adjust the bike to give you the best results you can get at that time on that day at that track, because your going around the same corners again and again ,next week its a different track.
On the road, you get a setting that carries your weight, is stiff enough to handle most bumps and gives good average handling. You can't set a bike up for the road like you do a track every corner is different
I've ridden bikes with no brakes , no suspension, no power, any bucket of shit you can get your leg over is great, just ride it as fast as you can with what you got, its still a challenge and lots of fun
Find a middle ground setting for the suspension, and you the rider make the rest of the changes
