RE: [TCML] How Important is Location?

```I cannot cite a figure for what difference might be expected.  The trouble is, with a static gap, one would have to carefully adjust the gap width to ensure identical breakdown voltage and bang size between the two altitudes, and few of us are equipped to do this accurately.
