Follow-up interview letter???

I have had 4 interviews for the same position within the last 3 weeks. I have sent follow up emails thanking for the opportunity for the last three interviews. I interviewed with 5 different people on the management team. Today was the final round of interviews meeting with the Regional Operations Directors. The interviews were quite different in my opinion I initially met with the Direct Supervisor and then met with Operations Director and Medical Director then met with their subordinates today. Should i summarize what was discussed in previous emails or provide what i call “last sales pitch “ as to why I am the best candidate for position based upon hiring manager’s position of what the role will entail. This position is ideal for my work/life balance and it’s what I love most about my career- Training and education of staff. Any thoughts are greatly appreciated!
