Issue with deep screw shots - hitting vs timing

Evening all,

Hope everyone's had a good day. Not been playing Snooker for long, started January this year and my cueing has improved massively since. One key shot I'm having trouble with is the deep screw - on shots where I need to screw the ball back some distance, I find myself "hitting" the ball rather than timing it, which often causes a miscue and the cue ball jumps. On softer screw shots, my I accelerate the cue nicely through the cue ball and have no trouble at all bringing it back, but when I try for a deep screw I find myself snatching at the cue and almost punching the cue ball rather than accelerating through.

My question is, are there any exercises I can do to improve my timing on the deeper screw shots? I've tried practising over and over but I end up getting frustrated which makes things worse. If there are any structured methods which gradually improve this issue, that would be great.

Thanks for your help.

Best Regards,
Ben.
