Eagle Vision Scope Rings (Calculating scope height)

Had a question. I’ve been using the eagle vision adjustable scope rings for long range shooting. 

When I lift the back ring it results in the scope pointing downwards. This helps in extending the range. I use StrelokPro and the software asks for the scope height (distance between centre of scope lens and barell) . After adjusting the ring rings, how do I calculate the scope distance for Strelok? 

Do I put in the new distance (distance between centre of barrel and ocular lens)? OR
do I take the average of the distance between the centre of the barrel and centre of the ocular lens and the distance between the centre of the barrel and centre of the objective lens? 
 
"Glem.Chally"Interested to hear a response, I thought of this exact thing when putting the data in for Strelok. I just averaged out the high side vs the low side but I could see that not being the right way to do it.
I tried the average too but it’s not accurate by any means. Strelok shows the wrong aim points using the average method.
