Second rate coatings ? The very best, the Zeiss and Leupolds, test at 95%. The average for all other makers usually runs about 92% for their fully multicoated optics. That 3% difference means nothing when compared to what a larger 50-56mm scope will do for you with more magnification. Try 20% closer to your target.
There was a time when this was much more significant than it is today. Back when Leupold's VariXII/III, for instance, were single coated, it would make some difference. You are looking at 84-86% vs. vs. 93-94% back then. Not hard to see that difference. E
