Ploting is something wrong?

I have 4 computers, 6 disks a little wrong, I did it all at once. Now the paths on 4 computers are from 0. From what I read it should look like this:
PC1:
D1 plot 1 - 100
D2 plot 100 - 200
D3 plot 200 - 300
PC2:
D1 plot 300 - 400
PC3
D1 plot 400 - 500

Do i understand correctly

And my second question, if I accept a second disk, the plotter should show me the range from 200 -300 and show me a bit differently:


Shouldn’t the plotter give a number between 7630256 and 15 260 512 ?
