If your Kebuki Rating is created from what your team members say, and they work for you - then why don't you just get them to mark you high and come away with a rockstar rating?
An accurate Kebuki Rating is there to help you be a better leader. Only by having an accurate Kebuki Rating can you learn what you need to do to improve.
Forcing your team to mark you high doesn't help you, and it tells your team that you REALLY don't care what they think of you - leaving you in an even worse position.
And ultimately - there is nothing that will give you a warm glow more than getting a Kebuki Rating of 80% and knowing that your team really do love you that much!
