As you wrote rrdtune does not rebuild HW related (more precisely: any) RRA-s. All changes get effective in the future. User have to wait on week or more to see if changes were succesful. Last year I planned an interactive GUI program to fine tuning of HW params. User could move some "potentiometers" and (s)he could see immediately what intervals of tested graph are find aberrant with the actual settings. But it remained a plan only...
