48FPS (2x source) is better than 24fps, 60 (to original monitor refresh rate is slightly better), 3x is even better, 4x is good, 5x is better than that, 6x is the best I've tried, after 6x
It is interesting method. To interpoleate first to one rate and then to blend frames to another rate. From your words:24 -interolate-> 48 -blend-> 60 (better) 24 -interolate-> 72 -blend-> 60 (even better) 24 -interolate-> 96 -blend-> 60 (good) 24 -interolate-> 120 -blend-> 60 (better) 24 -interolate-> 144 -blend-> 60 (dropped and delayed frames)Is it what you mean? right?
I mean the higher the framerate I can play, the smoother and less artifacts I see. Does that not make any sense? As a developer? Increasing the framerate doesn't correlate to how smooth a video plays?

Yes, then try for some anime episodes with 2x, you'll see it's not smooth enough.
Of course, you can try "to screen refresh rate" too, you'll see it smooth but with artifacts (Try the opening of Hitsugi no Chaika Avenging Battle, you'll see it)As anime doesn't have dynamic motion as same as live video movies.
The reason why MPDN drops frames but still looked smooth, it actually doesn't render with 5:2 multiplication, but it's closer to 2x multiplication by dropping frames (this is just my guess though)
Exact multiplication coefficient has always preferred for retaining smoothness and reducing artifacts.Here's the simple formula: smoothness ~= artifacts
If you get higher smoothness, the higher artifacts you get, and viceversa, if you lower the smoothness the lower artifacts.
Of course it's just in a simplified form, in implementation, you still factor many things like video fps itself, screen refresh rate, video dynamic motion, video quality (blurred video will harder to detect the edge), etc
I haven't watched anime for two years, I'm two years behind on naruto. But I do watch family guy and American dad and I watched the latest dragon ball z movie which came out (battle of the gods) in 720p (this was my best "anime" test, the higher the framerate the smoother it ran for me, 48fps on my 60Hz monitor isn't smooth, it's smoother than the original source at 24fps, but 96fps is when motion blur finally is almost eliminated and I'm left with a clear, sharp, fast moving image.
