My bud is only 51% humidity in the jars after trimming. How screwed am I?

I simply can't get the dry right. I keep it at 60% humidity and below 70F while drying so how the hell are the buds only 51%? They got dryer than the air around them somehow.

I watched a video where the dude said if you dry with RH at 60% or above it's a fail safe since it won't go below 60. That was a lie.
