So It's Back To First Principles

Hi VT,

For ref 690 we took the below picture and looking at the first step that is lower and the last one higher, therefore they compensate each other. An average 6 steps 7.5 Inch is giving us our 45". Is there another method we can be more accurate? I would be glad to change this height, but we need a more accurate source of some kind…

Maybe somebody should bring along a measuring tape to the next Trump rally?
