Just depends on your chosen method. If you're a MPBR guy, a flat trajectory matters. If you're a turret twister, it doesn't matter as much. As for me, I use both. I zero at 100 then dial to the MPBR for my load and if my shot exceeds MPBR, I dial as necessary.
I probably won't bother to tell Ron my thoughts on his video because it really isn't worth my time to do so. From the tone of your post, it's probably not worth my time to respond to yours either, but here I am…

Thanks BB for the video, kinda Ballistics 101 (w/o wind) but a good back to basics thing to revisit .
Concerning what Hondo said about the chosen method which is true I would add the area and conditions where you hunt can determine that chosen method. I strive to be set up for both methods as both have their place.
Where I hunt most of the time for Deer and Hogs in AR a flat as possible "point and shoot" (trajectory wise) rifle most of the time is best, I am talking about places that may have Highline R-O-W's or lanes that may allow in my area a 500yd. shot. For that hunting, ADVANTAGE = Flat shooter. I love my .257 Wea. or my 264 for that! In that situation I "range find" key spots for hold over, when a big Buck crosses you will not have time to range find him and then click up, trust me on that one.
For the area I hunted a great deal in WY. and other Western areas, the average shot can be longer and the area much more windy. Esp. if the area is more open then the Range, Click up and shoot comes into play more. And esp. if the yardage is 600+ yards and the animal is an Elk or big, I want a bigger cal. and a high BC bullet and all that. Then a round/rifle like my 300WM or my 6.5PRC with good click up optics matter.
Too many beginners I fear watch these "long range" shows and think you have to have a high BC bullet with a Click up scope and be ideal for their area when more often it won't be and esp. if there is a lack of trigger time.
To me if I had to have a simple chart: 0-400 yds. Advantage Flat shooter
400-600 yds. advantage flat shooter unless windy then BC, better yet a fast round with good BC
500-600+ BC
As always, a bullet that will expand and penetrate/terminal performance for the animal being hunted.
Long story short, only pay attention to everything!
