Default RE: servo arm length vs torque rating

From what I remember, they rate servo torque directly off the drive shaft. Every step out along the servo arm reduces the amount considerably.
And even worse increases servo slop, that tiny gear flex/slop at center that exagerated the further out along the arm you go.
I've always set up my pattern models with the push rod connected as close to the servo center as possible for both reasons.
I often look at the IMAC type set ups and think... Hummm may be Im wrong?
I'll still continue with my method... stuck in my ways.
