FWIW, I picked up the bow again this summer, going trad vs the compound last used in the '80s. I dropped back to 45# but have added a couple of bows since then that are in the 38 - 40 pound range. Most of the time I'm shooting a 52 recurve now.
I found Jeff Cavanaugh's you tube video to be a good help as well Merlin's Archery Adventures and a great gob of others.
Good Form should give some kind of group at 10 yards. Consistency of head position, shoulders, follow through on the bow arm (my worst recurring demon) and the release.
It gets there, somedays better than others. Shooting video of yourself can show you a LOT that you would otherwise think is 'fine'.
I wouldn't say dropping back to a lighter bow is needed, but it might help. If you are having trouble on the bow arm with your current one, it may be better with the lighter poundage.
On the release, if you are plucking the string you can drive yourself nuts too. The description of a proper release being, 'no longer holding the string'works.
Oh.. one more big help.. a deep hook versus a fingertip draw REALLY does help. Intuitively that sounds off, at least to me. However, there be some truth.
Check the area for Traditional archery clubs/groups or even a commercial range.
