Please help...can I still say I sell 100% of my listings?

Many years ago as a manager, I had a vision of training agents to sell 100% of all their clients homes.... after all wouldn't you want to hire an agent that sells 100% if the homes they list?  Of Course!  I had upper level management advise against this!  I can think of a few possible reasons why, but from a motivating factor alone, why shouldn't I try?(Corporate is locked into the stat that agents will only sell 50-60% of their listings).  In sharing with the agents I managed, I had a new agent whose eyes were not clouded by our industry standards, buy into my thinking so we were on our way!  She had pens printed saying, "I sell 100% of my listings", and through her I lived my dream and proof of concept!  She indeed sold all of her listings and was The Rookie of the Year for the #1 firm in our market and we did it in 7 months due to she was about to quit on me right before we started!

Now...she had me fired up and ready to walk away from the corporate world and provide a need for sellers which is HONEST MARKET ASSESSMENTS FOR SUCCESS and the past 4 years I HAVE SOLD 100% of my clients homes....meaning there have been a small handful, but they HAVE NOT been listed and sold by another agent!

I write this today marking a wrinkle in my 100% statistic!  Today I learned of the first listing in 4 years that I didn't sell has gone under contract with another agent:( Does this mean I can no longer tell someone I sell 100% of my  clients homes?  Please help me determine this as I am dedicated to providing honest and factual material and stats to people I meet everyday.

This client was like any other...I wanted to offer the highest level of service and sell their home in the shortest amount of time and for the highest price!  This is the ultimate winning combination into maximizing profit!  They knew me from previous transactions in the family....and obviously the homes had sold at the predicted value given!  Well, this time my proven success was shifted from professional service to a 'favor'.  They had requested I try to market the home for a price nearly $100K over my "prediction".  As reluctant as I was, I had a hard time declining.  I have turned down listings in the past like this, but I already had a relationship with these people and thought I would agree to share this time with them in hopes that they would see my value.  This home was challenging to price due to being unique and custom but I trusted my instinct.   As I thought activity was dead.  When it was time to consider our future, I was turned away for another agent at a lower price and due to their high level of 'marketing"....interesting enough...it was only reduced a few thousand dollars(still $50k over my "prediction) and still no activity or contracts!

Well....they went onto their 3rd agent and can you guess what price???  That's right....at the low range of my original figure 10 months before and over $100K under what they wanted me to list it at and now they have it under contract!  I'm very happy for them, but can I continue to market myself as an agent who sells 100% of his clients homes?  

I did give them my honest assessment in the beginning which was right where they are today!  If they had taken my advise, most likely the home would have had a 2-5 week marketing time vs. 13 months!  Time is money in selling a home so a year worth of expenses on the home would have been saved and ultimately the would have made more money!  

Even though my name will not be on the sold the sign, I will not be at the closing table, but the final numbers are what they learned 13 months ago.....am I still an agent that wants the best for his client and sells 100% of their homes for them?
