Freestyle Reduction nozzle vs steering nozzle

[loictahiti]

I saw somewhere on X, but couldn’t find it ......

If I bore my reduction nozzle to 90 mm , is it true I have to bore my steering nozzle to 93 mm, in fact each time 3 mm more .

Or my english is soo bad , that I understand a wrong thing

Thanks
