So I just got in a credo 2-10x36 and on the website it says there’s 26.2 mrad of total adjustment. Going up I can get 26 (3 full rotations of 8 plus 2 mrad). Now maybe if I was a more risky man I’d try for the extra .2 but I think you’d really have to crank it and break it. From the 0 going down I can go exactly 6.2 mrad. Now call me crazy but isn’t that 32.2 mrad of total adjustment? Maybe trijicon was purposefully only mentioning the “up” adjustment?
How to count travel distance on scopes

Toss the impact on it. Run it to the bottom of the scope then max out the elevation plus 2 Ugga Duggas. That’s your max elevation 
As @Steel head said. It’s never an exact amount. You’ll actually find most scopes have more adjustment than they actually list. At least that’s been my experience

Right and to a point I’m ok with that (this is sitting on a Mk12 mod h bastard) so I’m not anticipating using more than say 8 mil of elevation. I was just wondering if it’s then common practice for the “total adjustment” number in specs to be “up” adjustment total
No total adjustment will be top to bottom adjustment. You generally divide that in half to determine your usable elevation then add a sloped base to accomplish whatever usable travel you want for the anticipated shooting distance
So this was my understanding originally which is why I got confused. Perhaps just a happy coincidence that it has almost 26.2 mils up but given what you said about them usually having extra (in this case 6) that does make sense. Thanks!
