IMO it absolutely does matter. If you're shooting HFT of course you can't adjust your turrets or the magnification during the match. You have to utilize holdover. Sorry I'm not familiar with Strelok. I use Chairgun but I'm sure they share some of the same features and capabilities. In CG, I choose my zero to be the zenith. My KZ size is .01" as CG won't accept null. I have to put some value in. This gives me the flattest trajectory (least amount of holdover) possible.
As a point of reference, and all guns will be somewhat different, my BSA is 29 yards and my FX is 27 yards. And yes, I could use 30. The most important thing as JamesD. stated is to know your holdover (if shooting HFT) for every yard from 10 to 55. And yes, you can most certainty use other incremental values such as every 2 or even 5 yards. Just depends on the amount effort you want to go to and affirmation you want to have when you take aim and squeeze the trigger.
FWIW, I did a couple of videos on YT explaining range marking a scope wheel, zeroing, holdovers and bracketing your targets.
FT is a blast! you'll have a great time. Good luck!
