Rhythm is essential, imperative in my opinion.
I was hitting balls last week, one of those days when I felt "rhythm" and hit 100 balls really well no sweat and did not feel tired at all,actually felt had more energy afterwards.

Then few days ago, after hitting 10 balls, I felt NO Rhythm, I keep hitting balls thinking it would come. I tried to swing faster(faster tempo) or slower(slower tempo) but still no rhythm. It was real effort. The distance on my shots, especially the woods was a lot shorter despite trying to hit harder. My alignment and mechanic thoughts did not change from last week.
I keep hitting more balls... with different mechanical swing thoughts but....there was no change. After 100 balls I was physically and mentally tired.

Then after resting for a day, it became clear to me.....whatever mechanical pattern(swinging or hitting)and it's subset pattern you decide, make sure the rhythmic pattern matches the mechanical pattern. It's not simply one rpm, it's how the rpm's of each part of the machine work together,
