I'm a little mystified as to why it should be particularly complicated to collimate a Takahashi?

Assuming that the lenses were well centered and edged in manufacture ( the elements therefore having no `wedge') , and since passed a factory collimation check, then simple tilt of the whole lens assemble should be all thats required to return the scope to perfect collimation , and that can be adjusted looking at a star with a high power eyepiece whist adjusting the tilt. I thought that was one of the benefits of a refractor - freedom from any particularl complexity in collimation ?
