Let it soak overnight for stubborn spots.

Ever check alignment at different times of day, @the_alex? Temperature shift can trick your eyes before the laser level comes out.

Lol my paper sketches are a mess but it clicks somehow.

How did you have your pull string attached? I had the same fight with a pre-term last month. What finally worked was taping the connector tight against the cable with electrical tape to make a smoother bullet shape. It still caught a bit, but way less. @morgan329 I feel your pain on that added hour, it's brutal when a simple pull turns into a wrestling match. Sometimes a little extra prep on the head saves a ton of fight later.
