I have been watching and I do have to interject that the old tracking issue was with the mk4 and the CDS dials. The mk5 and up models have won many PRS and other precision rifle matches. The new CDS dial systems are much better than the old systems and track much much better, no these are not your 4k s ones for prs matches but instead are sub 2k scopes that are intended for hunting and recreational steel plinking!
