Something like that. The tweening can also be adjusted by the fps. But if you want to keep the FPS the way it is, make the movement on the segment of the stickfigure slowly, depending on the FPS.
Let’s say at 10 FPS; for three frames, make the first at the beginning, the middle at the second, and the last at the third. As for putting the segment in the middle, deter or estimate the distance between the segment on the first and third frame. Make sure that the distance for each is equal.

Here’s a tip for tweening: Since tweening guesses were the segment should go during the animation, make it easier for the tweening to guess where the segment is supposed to go by making the movement, frame by frame. And as an experiment, take a segment, turn it EXACTLY 180 degrees and use tween. Observe what you see, and repeat multiple times. Give me the results, and I’ll interpret them.
