My first brand new optic and some help with Strelok/Element ballistics App

Hello fellow shooters, backyard plinkers, paper assasins and test captains!
im very excited since thats my first post, for my first brand new west hunter 6-24x44 FFP. I could really really use some help!
I have done a lot of studying but seems i need help in specific matters. Im posting two pictures if the specs that came in the box with my scope.
I 'd need some help using the strelok pro (i can share it as i found it for free) or element ballistics app, seems i can't figure out what are all those info i have to register.Im also so fascinated for the masking tape on turret so i could use some help for this too
Its better for hunting and thats what im intenting to do!

Thanks in advance! Thanasis
