Optisan EVX SPF - dial or hold?

Can someone with the Optisan EVX SPF let me know if they recommend dialing or will the optic not be repeatable? 

I just got one today, seems crisp enough but I have my doubts- it's only a 350 scope, I will say though it's very clear and seems well made.

Would appreciate someone's advice prior to getting out the scope stickers and starting to calibrate. It's going to go on a .177
 
But what about the Scopes Joe has tested made in China with the click from Hell test and claims that it's repeatable and on the button. However doing it a few times when the scope is new is completely different than doing it after thousands of Cycles. I have read that some Vortex scopes that used to be highly regarded and made in Japan have shifted to being made in China now. I wonder if those still click well.
 
The FILIPINOS make THEM VORTEX tougher CLICKERS than China BUT! STILL NOT AS RELIABLE AS JAPANRSE TURRETS BTW! FEEL FREE TO CLICK CHINESE SCOPES. Nothing stopping you clicking Chinese scopes just don't be surprised when that unexpected sudden money shot goes astray potentially (GOD FORBID) damaging SOMEONE ELSEs property.
