First of all Huvius congratulations on a fine double...and excuse me for a moment while I clean the drool off my keyboard and the front of my shirt. I thought I had stopped drooling 57 or 58 years ago....reckon not.
It appears your elevation is close and that's a good thing. My experience with doubles has all been with rifles and I don't know how applicable that would be with a Paradox. One would think the same general rules apply. From that and what I've read you are correct, it needs to be slowed down. That, or a heavier projectile which would achieve the same result.
I think I would try two shots at 50 and 100 yards just to see what was going on there.
I will be interested to read what those more knowledgeable than me suggest.
