I have been to court with a couple of my sponsees over the years and have written more than a few letters to the court simply explaining that I know them in the fellowship and that they are putting in the time and effort. I have always been truthful, as of course we must and in some instances it has helped.
Best bet is a good fitting top for the bottle and a desire to not do it again, but if you have already made that determination for yourself then someone else's input may be of some value when the court makes its determination.
Just my experience. However I will say that I have never written a SECOND letter for anyone.
