I have failed at pocketing rail cut/kick shots at >= 90 degrees but I noticed you added some draw to the inside english. I will try that out.
The video's start with nearly 90 degree cut shots showed that these are best done and not impossible with easy aiming such as cue ball really close (three inches?) from object ball. Maybe the bigger problem for some shots is making sure the cut is less than 85 degrees. I have some trouble eyeballing the degree cut shot for object balls close to the pocket and not on the lines between corner and side pockets.
I was surprised at how fast you hit the cue ball and, still, enough spin-induced throw occurred to pocket object ball. The faster speed was necessary for object ball to reach pocket.
There is only so much I can get from AZBilliards. I don't recall discussions here of jump and bank shots that let you pocket more than >90 degree shots. Your video packed in several minutes what would take extensive discussions and excessive verbal abuse to learn here.
