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?
