I just worked through this problem on blinds. It was an issue i caused from expecting to run perfect lines and me nagging him and calling back to start over. Went back and started over at force to pile and built up confidence . Lots of marked pattern blinds. Went slow and now it has all but gone away maybe one spin per week but that is also a handlers issue when i dont confidently send him. It was all my fault from trying to go to fast and expecting to much and not teaching him. I at times push to hard and now also read him better and know when to quit when we are ahead.
