Hi Glen,
Which offset are you referring to? Is it the one towards the primary mirror or the one away from the focuser? The first one is important and as I mentioned is taken care of when the secondary mirror is centered under the focuser regardless of the scope's F-ratio. The second one is not important except for the few cases I have listed.
