I did nto say you combined,
I said you frame jumped to use different measurements
than all from one frame to see what actually occurs
outside the box.

That's not frame jumping. It's okay to look at what
observers in other frames are seeing from their
perspective -- provided you don't mix untransformed
(where required) measurements from other frames.
Frame jumping is the "illegal" mixing of untransformed
quanitities.

In Newtonian mechanics a there are a number of quantities
that require no transformations (mass, length, force,
time).

You jump in the box when the measurements outside
frighten you and your church.

What church is that James? We're not doing any
Relativity here, so it's not the Church of the
Rubber Ruler! So now are you saying that your
much cherished classical Newtonian mechanics is
broken too?
