string stretch question

[portugeejn]

I made a couple B50 flemish twist strings for my Martin Serengeti 62".  The fast flight (I think) that came with it measures 59".  The strings I made measure 58 1/2" (when they are off the bow).  The brace is set the same.

Does that seem right?  I know that the B50 stretches, but does that sound normal?  Thanks for your opinions.

That is right in the ball park.........the B50 could be a half inch shorter.
