I’ve tried using the clamp as you’ve suggested and while it was an improvement in other ways it didn’t fix the problem. I also noticed how the Get World Rotation has the format from -180 to +180 whereas the view yaw min/max goes from 0-360 which may be the source of the problem. To fix this I tried to combine the clamps with make rotators as per this discussion Rotation negative after 180 degrees and again it improved the precision of the desired view restriction but ultimately it didn’t fix the main problem either.
My blueprint looks like this now:
