Typical expectation seems to be that reducing object "lookups" (ie. fewer
'dots' to get to the particular object) leads to better performance.

An example showing the two different methods you're considering would
help.
Also -very easy to test...

My expectation is that Offset would be faster because there would be less
object lookups/assignments.

Performance difference would depend on the particular algorithms used and
coding skills.
