I may be wrong but it looks like your 1st setup calls for something like 1/8 ball cut to make the pocket.
My 3C game is mostly about clocking and this semi-thin cut is one I'm working on developing more control/understanding. Work in progress but is now 1 of 3 standard hits or strategies. The other 2 are 1/2 ball and a hit that sends my CB perpendicular to a rail.
Once you do the work/study on Exact tip placement that gives you 1, 2, 3 diamonds spread when shooting diamond to diamond across the short table (perpendicular to a long rails) you'll have something to work with regarding the described hits.
I just discovered the 1/8 ball hit and the control I can get from it. It's re-ignited my interest. Getting old. Wish I knew more about clocking 40 years ago.
Simplified Clues:
1/2 ball hit determines CB 3rd rail contact point. 2 o'clock or 2 tips brings CB to 2nd diamond on the 3rd rail.
With a thin hit that sends CB perpendicular 90degs into a rail gives you your study results on tip placement. Kinda. There's work/study needed here since depending on needing inside or outside English, spin is added or subtracted from the CB.
Hard to describe the 1/8 ball hit since its work in progress but with the thin hit the math is whatever gives you 1 diamond spread across the short long rails will give you 2 diamonds spread down the length of the table.
With the 1/8? ball hit some of that calculation goes out the window. Sorry I can't explain this better. I'll just say I have better confidence where my CB is going, if I make the hits and my cue is straight.
Fortunately I don't have to worry about pocketing balls, just having fun with the CB is enough for me.
