IMO the bud density varies too much to rely on a moisture meter reading of a branch, a hygrometer in a jar or bag after taking the buds off the branches and storing them works much better. Or just a few buds worth in a jar as a test of when to buck the buds off the branches. The hygrometer I use is something like $20 for 5 off Amazon. They do vary in readings by two or three percent but good enough to get you in the ball park with some experience with them.
I recently left my hang go half a day too long and the buds read 54%. I took a small square of paper towel, wet it and squeezed the heck out of it and put it in the tote with the dry buds.
Next day up to 64%, a little higher than my goal of 58-62%.
The only thing you have missed out on is a long, slow cure from ~ 70% down to ~60%. It will cure some in storage but not in the same way.
How I dry/cure my harvest
